I just downloaded this and have had no bad experience with it. certainly not simple as utorren UI wise but certainly for the more savvy torrent user.
I'm also new to Tixati, been using it for about 3 weeks now. I like it better than utorrent, I don't miss any of its features. And I actually got a slight increase in speed also (might be because I got the configuration right this time, don't know). Overall I'm very happy with it. Clean, simple, doing its job, like the old utorrent.
