I'm trying out Gregarius rather than Bloglines. It has the advantage that I have the code so I can hack at it, and seems to have mostly the same functions, but I haven't made up my mind yet.
I recently switched to Gregarious myself. I also find it to be much faster and more stable than Bloglines. Bloglines javascript used to freak out on me a lot. . . . I am quite happy with Gregarious so far.

I've hacked it to behave a bit more like the aspects of Bloglines that I like such as paging through unread items on a feed by feed basis.
