What is the best torrent software?

[Knapp]

I was looking at all the torrent software. There seems to be a lot of them.
Deluge, Bittorrent, cTorrent, rTorrent, ktorrent and others. I see it
as a plus if I can use it on the CLI. But which is the fastest? Which
has the most features? Thoughts?

Also for settings? I use encrypted settings now and that seems to
result in faster downloads but there are a lot of other settings that
might speed things up.

Thanks all!
