Is there a list of the top Life Insurance companies?

Doing research into which life insurance companies are good to work with. Is there a list of the top or best ones?

Nope. Top means something different to lots of people. Biggest sellers? Most policyholders? Fewest complaints with the state? Fastest claims service? Fewest claims denied? Highest pay for salespeope? Most friendly to working moms?

See what I mean?
