The bottom line
USAA
USAA earns an overall score of 4.86/5 in QuoteYeti's car insurance provider rankings. The carrier ranks #1 nationally, with particular strength in affordability.
USAA is best suited for drivers who prioritize the lowest possible rate. Membership restricted to active-duty military, veterans, and immediate family members is the most common drawback to weigh against the strengths.
As always, compare quotes from multiple insurers before committing. The right carrier depends on your specific profile — driving record, claims history, location, and coverage needs all shift the math.
Mercury
Mercury earns a quote if you're in California or one of its other operating states and price is your dominant criterion. If you're outside its footprint or you'd trade a few dollars per month for better claims experience, look elsewhere.
