Friends, what #email client are you running on #Linux these days?

I've been running #Thunderbird since... the beginning?

The last few weeks I've tried a few other clients. #Evolution is decent but the GUI is stuck in the past, rough edges, clunky.

#Geary is ok. More modern but a little simplistic and I can't seem to find a way to disable threading (do not like). Graphically slow as well it seems.

What graphical client are you using that you like? What is it that you like about it?

Boost?
