Apparently I'm the devil's advocate. I had good luck with Geico in the past.
I've also called other companies and had them tell me to stick with Geico when they couldn't beat my rate.
The main reason I no longer have Geico is that I moved to MA, and MA has weird auto insurance laws. I don't believe I could use Allstate or State Farm here either.
I was involved in a couple accidents that weren't my fault, and a couple that were while I had Geico. Both at-fault greater than my $500 deductible, too.
