Based on LibTorrent, Lots of features, easy customization, web UI is consistent and stable, API is easy enough to work with.
Plus it generally works everywhere I need it to - as a GUI app (across all major OSes), a web app, or a terminal app. So I can just dump it on whatever machine I'm using without having to think very hard.
Transmission is also fine, but it kinda felt like it was stalled out for a bit - missing features, some ui bugs, not much movement around it. So I switched to Deluge and haven't really had a reason to move anywhere else.
