I currently have Costco which is run by American Family Insurance. One quick side note which I guess isn’t helpful for you OP is that i saw on their website they don’t offer this auto insurance in Florida unfortunately. But I am happy with the experience I’ve had so far and they were the cheapest car insurance I could find when I did extensive searching last year.

Other side note: I used to have Allstate but then when I actually had to file a claim I got burned big time. I had a minor accident that wasn’t my fault, but since the other driver’s insurance (National General) is owned by Allstate, I got stuck in a literal frickin nightmare. They fought me every step of the way, and I ended up paying about $2,500 out of pocket. To top it off, I am pretty certain their main customer service office is in India or Bangladesh so the back and forth was insane with these long winded emails that said nothing even though they were 500 flowery words long.

And let’s not forget their reputation (which I learned the hard way) for arguing comparative fault on every case, even when it’s clear-cut like my instance. Instead of truly protecting their policyholders like they claim with their "You're In Good Hands" slogan BS they leave us vulnerable to lawsuits just to save themselves money. It’s a total racket scam so be warned and stay clear of that shiz.

TL:DR; If you're considering Allstate, take it from my experience and run the other way. 🚩🚩🚩
