Most of the features present in other BitTorrent clients are present in µTorrent, including bandwidth prioritization, scheduling, RSS auto downloading and Mainline DHT (compatible with BitComet).
Additionally, µTorrent supports the Protocol Encryption joint specification (compatible with Azureus and BitComet) and peer exchange. µTorrent was written with efficiency in mind. Unlike many torrent clients, it does not hog valuable system resources typically using less than 6MB of memory, allowing you to use the computer as if it werent there at all.

Skinnable and Localized
Various icon, toolbar graphic and status icon replacements are available, and creating your own is very simple. µTorrent also has support for localization, and with a language file present, will automatically switch to your system language. If your language isnt available, you can easily add your own, or edit other existing translations to improve them!

Actively Developed and Improved
The developer puts in a lot of time working on features and making things more user friendly. Releases only come out when theyre ready, with no schedule pressures, so the few bugs that appear are quickly addressed and fixed.
