I had Foremost through Farmers. I compared policies with All State, and All State came out the clear winner, even though I was getting a "multiple vehicle discount" from Farmers (two cars and two motorcycles). I now pay much less for the same coverage on the bikes. No claims, so can't talk to that, but All State is a well known company.
I checked into the back story on Progressive and didn't care for their leanings. Nuff said.
