I've actually had better luck with Vuze than I have had with Transmission. That, and Transmission doesn't offer even half the configuration options I've seen in Vuze.
Call me a die-hard fanboy, but I use Vuze quite regularly, and it's one of the first packages I install with every new Linux/Windows installations, sometimes not even on my own computer (I have a few friends who've now become die-hard fanboys like me because of it).
There's a bit of a hiccup that occurs occasionally in Vuze for Mint, because the Vuze in the repositories is actually an older version, and it sometimes gets stuck in a download-restart-update-forget it updated-restart again loop, but this is easily fixed by editing one of the config files. Let us know if this happens and I'll walk you through fixing it.
