I used Thunderbird and Enigmail for a year or so. I later moved to Evolution for the better GPG experience (no flickering on opening the message as there is with Enigmail) and better GNOME integration. I used Evolution for another year, but its rough edges wore me down; I had to get in the habit of closing it if I wasn't using it, because it would noticeably slow my system down. It would take at least 5 seconds to open. Parts of the UI would often lock up and need a reset by switching between the panes.

I've been using Claws Mail for the past few months. It's simple, fast and stable, and GPG support is fine. That's all I need. It sucks for reading and writing HTML emails, but I'm okay with that. Parts of the UI are still rough (e.g. the main window isn't responsive while the "sending" dialog is open), but it's less worse than Evolution.
