Changing Insurance to State Farm, your input requested

I have had State Farm for years and have been very satisfied with their rates and service. I keep hearing these claims that XX company can save you hundreds of dollars, so I ask for quotes and not one of them has been able to beat SF rates. Having the house, car, motor home, golf cart, boat, and personal liability all with them helps with the rates also. I tried the Independent agents also and they haven't been able to beat State Farm either.
