I like WebTorrent especially for movies, because you can watch immediately without waiting for the torrent to finish downloading. My fork adds leech mode to stop upload right after download finishes, does not send telemetry and a few other changes.
Actually, WebTorrent has a lot more features. You can download directly in a web app, making a “CDN” of sorts. They also have an instant file sharing where you can create a torrent and share it through instant.io with anyone with a web browser. I really like this project. My fork is just a small personal tweak.
