Anyone have recommendations for Thunderbird alternatives?

Maybe just a case of: This thing is bad, but all the alternatives are not any better

I've been using Thunderbird almost as long as it has been available. Still using it. Every once in a while I attempt to look at alternatives. For the most part, Thunderbird works for me and I have strongly recommended it in the past.
