I am way to stubborn to drop an anime but I do admit t dropping 2 anime and those were steins gate , I eventually got into it and it was amazing and the second I don't even remember (which is the bane of my existence because it nags at me every day). I can't live with my self if I don't finish what I started plus I hate not giving an anime a chance to show its full story , there might be some good points in there that completely turn everything around for you.
Though I do agree waiting for a week for an episode of an anime you just don't enjoy feels like waiting to be punched in the face by your least favorite person on earth.
I used to use both as well, but I only tried Azureus after they became Vuze. About uTorrent though, if you don't have the paid version, you should definetly check out this article:
