State farm has been awesome to me. I have made more claims on my trucks comprehensive (stupid thieves) than I have paid to them for the coverage! There rates are a little higher but there service is worth it.
USAA They are mostly involved with Insurance & Investments
It's a very good Insurance Co. and are very fast on claims. Another bonus is that almost every year I get a check back based on their yearly divideneds & how much my primium is or something... It's usually a $250-$300 check which covers just over 1 month's ins. payment.
