I use utorrent under wine. I'm sorry but its the best by miles and runs like a native linux app.

The far-and-away best torrent client on any platform is rtorrent. It's the fastest, most stable, and consumes the fewest rtesources. The ONLY downside is that it's CLI-only. This makes it nice for administering remotely since opening an SSH session is trivial to initiate, but it does mean there's a learning curve.
The maintainer of µTorrent tests it for complete compatibility with WINE, so if you're on an x86 platform it'll work well. If it's what you want to use I see no reason to switch.
