I love stars. I'm up $222.42 in the last week multitabling on the $0.25 tables.
Last night I lost $25 in 1 hand when I got all in with AA vs KK. I had the best of it but a K came on the turn. A couple of hands later, this happened on a different table...

But I've just recently started playing on other sites and so far I still think Stars is the best. I hate the interface on UB and I hate how slow the party software is.
