Agreed. I've been a longtime user of Thunderbird, and only a casual user of mutt when I've needed to do some quick processing of email on a server or over a slow connection. But my latest upgrade to Thunderbird 3 has been very disappointing, with continual freeze ups, extensions not loading, and too many restarts required each day where previously I'd let it run for weeks at a time. So I tricked out mutt with complete configs for my IMAP accounts and RTFM. I must say, I'm impressed and feel like I made a huge leap forward. I now have an email processor, not just a point-and-click dartboard. Still, it's not perfect, and I don't think any email client can be.
