Project Management tools with great UX?
The more I look for a project management tool, the more I'd appreciate a tool / service with a great UI / UX which seem to be quite hard to come by. So far I've tried:

 - JIRA - don't like it at all (but my perception might be influenced by the fact that almost every instance of JIRA I've tried has been slooow)
 - Assembla - typical old-style UI (busy interface, not great fonts etc.)
 - Codebase HQ - they are trying to look better but I still find the UI busy and not very straightforward
 - Trac - I actually find their UI quite OK
 - YouTrack - didn't particularly liked it
 - Unfuddle - I've only used their discussions but they were quite well-designed
 - Basecamp - I liked it
 - Pivotal Tracker - interesting UI doing what it's been built for but I'm not sure this can be considered a full-featured PM tool in itself.
 - TFS - at least its integration in Visual Studio seems OK to me

I also looked at screenshots of FogBugz but almost any tool looks good on screenshots :) I probably won't go with FogBugz because of the relatively high price.

Do you know of any other PM tool / service that would be worth trying and could surprise me with a great UI?
