I get very good results using Azureus.
Only issue with Azureus is you need to keep your share ratio up. If it drops below 0.7 I think it is, then Azureus seems to slow downloading down until uploads catch back up. My ratio is over 2.0 now so it's reasonably safe. lol

If your share ratio is poor, some people actually filter users out who have poor share ratios to rid of leechers via their torrent program settings. And some people have these requirements quite highly set.

LW is not accepted as a proper torrent program at a number of torrent sites. Also, not a lot of control over how you manage the torrents in LW.
