Utorrent 1.6 is better by far, imo, unless you need the extensive set of features available for Azureus.

I used Azureus for years - got tired of the bloated, slow performing enormity of the app. I heard about Utorrent, and tried it, and now at 1.6, think it is the best solution out there for most users, again, who don't need those advanced features.

I'm totally biased now. Used to be an Azureus fanboy, now I'm totally in favor of Utorrent.
