I've had State Farm Home and Auto Insurance for 10 years now and I've been very satisfied with State Farm insurance company and will likely stick with State Farm for as long as I'm alive or as long as they're in business.
State Farm is also at the top of the list of being insurance company with the highest customer satisfaction.
The other good highest rated Insurance companies are Liberty Mutual, Esurance, Allstate, USAA, Geico and The Hartford.
