Bitlord was my former beast, but then I turned to Azureus, because it reminded me of Limewire hehe. Azureus is honestly the easiest one to use, which is why so many people prefer it.
Currently I use Araditracker, which is a private torrent client. You get to download after sharing, because torrenting is actually just sharing.
The more you share, the better your rating, and through this, the quicker you download, and the more you get to download.
I love it personally
