T.S.
I've been a licensed insurance agent for 17 years (ouch, I feel old!). My mom just started her own insurance agency and my sister works at a different one (doing health insurance).
I obviously have access to have many insurance companies and I quote my home, auto and umbrella annually. That being said, with the 8+ companies I have access to, my insurance is actually with ERIE Insurance. They offer great rates and we, unfortunately, had two claims with them and the claim service was excellent.
If you truly want to compare with many companies, then I suggest contacting an independent insurance agency as they will do the comparing for you. If you are interested in getting a quote from either my mom's office or my sisters, please send me a private message.
Good luck.
