I have had aim tritron for a while now. You will find it is slow because all of the gui, it seems hard to delete offline buddies from your list, you have to go through a ordeal to show the entire buddy list offline and then you can delete it. So the mgmt of your buddy list can be a bit annoying, other then that it's ok.

I mainly use it for chatting, I don't need all of the other goodies that comes with it, so they basically slow me down and get in the way.
