GEICO, Allstate, State Farm, and Progressive together insure the majority of U.S. drivers. They’ve each been around for nearly a century, and they all have real strengths — but “biggest” doesn’t mean “best for you.” This is an independent comparison backed by the Nerd Score, our own first-party rating computed transparently from sourced data across four pillars: Price (30%), Claims (35%), Coverage (20%), and Digital (15%). We take no money from the carriers we rank — see our methodology.

The Nerd Score: How the Big Four Rank
Here’s where the four land on the Nerd Score (0–100), with the underlying pillar inputs (each 0–10). The scores are not hand-set — each is computed by our published formula from the sourced pillar data below.
| Carrier | Nerd Score | Avg. premium/yr | Price | Claims | Coverage | Digital | Best for |
|---|---|---|---|---|---|---|---|
| Progressive | 80 | $2,006 | 8.6 | 6.2 | 9.1 | 9.4 | Higher-risk drivers, coverage breadth |
| GEICO | 78 | $2,055 | 8.4 | 6.9 | 7.5 | 9.3 | Best overall value |
| State Farm | 78 | $2,120 | 8.2 | 7.5 | 6.7 | 9.4 | Agent service, claims |
| Allstate | 68 | $3,176 | 4.4 | 6.8 | 8.7 | 8.9 | Add-on options |
Pillar inputs are sourced (see “How we scored these” at the end). Premiums are national full-coverage averages for a clean-record driver and will differ for your profile.
The headline: Progressive edges out the field on the strength of the widest coverage menu and a competitive price, despite having the weakest claims-satisfaction score of the four. GEICO and State Farm tie at 78 as balanced all-rounders — GEICO a touch cheaper and broader, State Farm noticeably stronger on claims. Allstate’s score is pulled down hard by price: at a national average of $3,176/yr it’s by far the most expensive of the four, and no amount of coverage breadth fully offsets that in a price-and-claims-weighted score.
What Insurers Actually Measure to Set Your Rate
Before the company-by-company detail, it helps to know the variables that drive your premium at any carrier:
- Location — state regulations, local claim frequency, and weather all affect price
- Vehicle type — make, model, age, and repair cost
- Driving history — accidents, violations, and prior claims
- Age and years licensed
- Credit score (in most states)
- Annual mileage
- Marital status
- Coverage level selected
No two drivers pay the same rate, even with the same carrier. Use the company-level comparisons below as a starting framework, then get actual quotes.
GEICO at a Glance — Nerd Score 78
Founded in 1936 as the Government Employees Insurance Company, GEICO has grown into one of the largest personal-lines insurers in the country. It operates largely direct-to-consumer, which helps keep overhead (and prices) low.
Nerd Score 78 · Price 8.4 · Claims 6.9 · Coverage 7.5 · Digital 9.3
Best for: Price-conscious drivers; tech-first customers.
Key strengths:
- One of the lowest average premiums of the four ($2,055/yr national average) — its 8.4 price score is second only to Progressive
- A top-rated mobile app (9.3 digital) with vehicle monitoring and roadside locator tools
- Mechanical breakdown insurance — an add-on the other three don’t offer
Notable gaps: A middling 6.9 claims score (just below the J.D. Power segment average) and no gap or new-car-replacement coverage hold the coverage pillar to 7.5. For a deeper breakdown of GEICO’s discounts and coverage menu, see our full GEICO review.
Allstate at a Glance — Nerd Score 68
Allstate launched in 1931 and has long positioned itself as a full-service carrier with an extensive local-agent network. Its coverage breadth is genuinely wide — but it’s also the most expensive of the four, which is what drags its Nerd Score to the bottom of this group.
Nerd Score 68 · Price 4.4 · Claims 6.8 · Coverage 8.7 · Digital 8.9
Best for: Drivers who want maximum coverage options and prefer working with a local agent.
Key strengths:
- A broad policy menu — gap insurance, new-car replacement, and accident forgiveness — earning the second-highest coverage score (8.7) of the four
- Drivewise telematics can yield discounts for safe drivers
Notable gaps: At a $3,176/yr national average, Allstate is the priciest of the four by a wide margin — its 4.4 price score is the single biggest reason its Nerd Score (68) trails the others. Because the Nerd Score weights price at 30% and claims at 35%, coverage breadth alone can’t close that gap.
State Farm at a Glance — Nerd Score 78
Founded by a farmer in 1922, State Farm is the largest U.S. auto insurer by market share, with a large agent network nationwide. The agent-centric model means personalized service is a genuine differentiator.
Nerd Score 78 · Price 8.2 · Claims 7.5 · Coverage 6.7 · Digital 9.4
Best for: Drivers who value agent relationships and claims service; teen drivers.
Key strengths:
- The best claims score of the four (7.5) — the only one above the J.D. Power segment average — which matters because claims is the most heavily weighted pillar (35%)
- A top-rated app (9.4 digital) and a competitive $2,120/yr average premium (8.2 price)
- Drive Safe & Save telematics rewards low-mileage, careful drivers
Notable gaps: The narrowest coverage menu of the four (6.7) — fewer optional endorsements than Allstate or Progressive, and no gap insurance — which is what keeps it tied with GEICO at 78 rather than ahead.
Progressive at a Glance — Nerd Score 80 (top of the field)
Progressive has been innovating in auto insurance since 1937 — it introduced drive-in claims, installment premium payments, and online policy management long before competitors. Today it’s known for transparency (its “Name Your Price” tool) and for serving drivers others shy away from.
Nerd Score 80 · Price 8.6 · Claims 6.2 · Coverage 9.1 · Digital 9.4
Best for: Higher-risk drivers; comparison shoppers; specialty-vehicle owners.
Key strengths:
- The widest coverage menu of the four (9.1) — including gap insurance, accident forgiveness, and rideshare — and the best price score (8.6) at a $2,006/yr average
- A strong app (9.4 digital) plus the Snapshot telematics program and the Name Your Price tool
- Covers a wide range of vehicles: boats, ATVs, motorcycles, commercial trucks
Notable gaps: The weakest claims-satisfaction score of the four (6.2) on the J.D. Power study. Because claims carries the heaviest weight (35%), this is the one thing keeping Progressive’s lead over GEICO and State Farm narrow rather than decisive — and the reason a driver who prioritizes claims handling might still prefer State Farm.
Head-to-Head Comparison
Coverage (Nerd Score pillar — 20%)
On documented optional-endorsement breadth, Progressive leads (9.1), with Allstate close behind (8.7). Both offer gap insurance and accident forgiveness; Allstate adds new-car replacement, Progressive adds rideshare. GEICO (7.5) is narrower — no gap or rideshare — though it’s the only one of the four offering mechanical breakdown insurance. State Farm has the narrowest menu of the four (6.7).
Pillar winner: Progressive (9.1)
Claims (Nerd Score pillar — 35%, the heaviest)
Claims is the single most heavily weighted pillar because it reflects what the insurer actually does when you file. Our claims scores map to the J.D. Power 2025 U.S. Auto Claims Satisfaction Study (1,000-point scale, segment average 700):
- State Farm — 7.5 (study score 716, the only one above the segment average)
- GEICO — 6.9 (697)
- Allstate — 6.8 (693)
- Progressive — 6.2 (673, the lowest of the four)
So while Progressive wins the overall Nerd Score, it’s State Farm that leads where it matters most — claims. That’s the core tension in this comparison.
Pillar winner: State Farm (7.5)
Price (Nerd Score pillar — 30%)
Anchored to a national full-coverage average of $2,320/yr for a clean-record driver, the four carriers’ average premiums and resulting price scores are:
| Carrier | National avg. premium | Price score |
|---|---|---|
| Progressive | $2,006 | 8.6 |
| GEICO | $2,055 | 8.4 |
| State Farm | $2,120 | 8.2 |
| Allstate | $3,176 | 4.4 |
Progressive and GEICO are the cheapest of the four; Allstate is the outlier
Rates are highly individualized: a 30-year-old with a clean record in one state may find GEICO cheapest, while a different profile might do better with State Farm. But on the population-average data, Progressive and GEICO are effectively tied at the top, and Allstate is the clear outlier. If you’re a low-mileage or telematics-friendly driver, it’s also worth comparing newer usage-based insurers outside the big four — our reviews of Root and Clearcover cover two app-first carriers that price heavily on driving behavior.
Pillar winner: Progressive (8.6), GEICO close behind (8.4)
Digital (Nerd Score pillar — 15%)
Scored on blended Apple App Store and Google Play ratings, the four are tightly bunched and all strong: State Farm and Progressive 9.4, GEICO 9.3, Allstate 8.9. GEICO’s app is widely praised for vehicle monitoring and locator tools, but on the store-rating blend State Farm and Progressive edge it out by a hair.
Pillar winner: State Farm / Progressive (9.4)

Bottom Line
There’s no single “best” auto insurer — the right answer depends on your driving history, budget, coverage needs, and how you prefer to interact with your carrier. But on our sourced, independently computed Nerd Score:
- Progressive (80) tops the field on the strength of the widest coverage menu and the best price, and is the pragmatic pick if your record isn’t spotless — just know its claims-satisfaction score is the weakest of the four.
- GEICO (78) is the balanced value pick: second-cheapest, a top app, and broader coverage than State Farm.
- State Farm (78) is the choice if claims handling is your priority — it’s the only one of the four above the J.D. Power claims-satisfaction average — and you value an agent relationship.
- Allstate (68) offers wide coverage but the highest average premium by far; its score trails because the Nerd Score weights price and claims most heavily.
