I’ve tried most of these clients, but I keep going back to uTorrent 2.2.1 (the newer versions are indisputably awful). I find that it still has the best UX to date. On nix machines I use qB.

I haven’t updated utorrent since 2012 and I’ve never noticed any differences. I have it setup how I like it and it works.

Not updated since 2012? How is it not full of security holes?
