I'm still on my quest to ask a Q in every category.
lol,at this rate it will probably take me about 2 years to finish.

The best insurance companies are the ones that pay claims when they are supposed to.

The A.M. Best Company, an independent rater of insurance companies, assigns a grade to the financial strengths and claims-paying abilities to insurance companies.

A.M. Best's top rates are A++ (Superior), A+ (Superior), A (Excellent), A- (Excellent). The next ratings are B++ (Good), B+ (Good), and they go farther south from there. The A.M. Best Company has been in business since 1899.

So, to answer your question, the best insurance companies will have the highest ratings. Otherwise, steer clear.

Car Insurance
I had Erie Insurance for years and they were awesome. Moved to Florida last fall and they don't service this area so now I'm with State Farm. They've been okay so far.

Life Insurance
MetLife is a good one. They also have investment plans as well.
