Deluge

It's not uncommon for really successful applications on certain operating systems, such as Linux, to release new versions for Windows and Mac as well.

A clear example of this is Deluge, a free and open-source P2P client that has been specializing in BitTorrent downloads for several years, which is one of the most widely used file exchange networks in the moment.

Its interface is clear and simple, and it has many options so you can adjust it to your needs, both in terms of the connection and of file management.

Apart from that, Deluge lets you install add-ons, which can give you more features to those already included in the application.
