Torrent clients for Mac other than uTorrent

Can someone recommend a good torrent client for the Mac, other than uTorrent? [The only problem I have with uTorrent is that occasionally it doesn't respect the upload limit. This is a known issue, and no setting seems to fix it in my case.] I am looking for these features: 1. Ability to select files to download (in case of multi-file torrent) BEFORE the download begins 2. Show transfer rates in the dock icon 3. Assign relative priorities to files within a torrent 4. Good, clean UI (optional) 5. No bloatware/adware like a built in media player, ads, yahoo-search-plugins, etc (optional)
