I'd like to know this, too. What sets it apart? I'm especially curious about performance, because both Deluge and qBittorrent chug a little bit on my machine when I have too many torrents listed.

Qbittorrent recently introduced sql based resume file it is advanced option in beta I see an improvement with about 1000 torrent. Though for 1000+ torrents most people recommend rtorrent.

You can limit qBittorrent pretty nicely with a cgroup if you're on Linux. It won't crash and won't lose much performance.

I'm forcing it to use between 75 and 125MB and it doesn't complain.

Note: I'm using "nox" variant as a user service and control via a web browser.
