I've had no problems using Azureus/Vuze on both Windows and Linux machines, my Linux machine is pretty low-powered overall and doesn't have any problems running it. When I ran torrents on Windows boxes I didn't have any real issues either (I had other issues with Windows, but that's another story).

I've used uTorrent on Windows machines, and it runs fine, but I didn't find any reasons to prefer it to Azureus.
