Utorrent has been indisputably the best Bit-Torrent client for Windows due to it's light-weight resource friendly interface and simple usability almost since the 1.5.0 release, or perhaps since even much before. When it comes to linux, selecting the "best" Bit-Torrent client has always been a n-sided affair. Bit-Torrent, Transmission and Ktorrent are some of the most popular torrent clients used across the Linux community. Azureus, which was the only reliable client for windows available before Utorrent, is also only a bit behind, mainly because it is Java-based. Other less popular clients include CTorrent, Deluge, Torrent Swapper etc. Of all only three worked comfortably on my system on PCLinuxOS Minime 2008. Somehow Bit-Torrent kept crashing and the others weren't even worth mentioning.
