Review & Alternatives: Best Free BitTorrent Client

Pros & Cons:

Low and stable RAM and CPU with all the necessary features. Fastest performance on torrents. Development still seems to be very active and responsive to users. Clean install, no addons etc. Cross platform client.
Support has improved, but could be better. Not that well known and not accepted at many private torrent sites (though the situation is improving).

Our Review:

qBittorrent is the choice for those users that just want to download torrents and are not interested in graphs, extra information and display. qBittorrent tested slightly faster on the test torrents consistently. Its RAM and CPU usage makes it the most efficient client here.

It has all the features that an ordinary user would want. Their built in search runs quick and has a good number of sites included at default. I am usually not a big fan of built in searches, but this one is superior to the rest. Plugins for additional sites are available.

The Wiki has improved, but is not among the best. The situation at the forums is good. Response at their bugs page is excellent and the responses are from the developer.

qBittorrent has been the Editors' Choice here at Gizmo's Freeware for a few years and was only a sliver behind Tixati this year. This is an excellent client that is fast with all the features an average user needs with small CPU and RAM usage and a clean install.

I said it back then, and I still think qBittorrent is the best torrent client around.
