there is no best or the best of the best when it comes in bittorent clients. as far as memory usage is concern, utorrent is the lightest (as what im using now) and if someone think limewire is safer than bittorent, think it again (or lets say google your question) then if your looking for the best downloading way in the internet, use USENEXT (but there is a fee) but its really worth and asking what you can download in bittorent.... try to visit and search what you looking for piratebay isohunt mininova meganova torrentportal demonoid (need invitation to be a member) and many more private trackers but mostly needs invitation ;;;; what im doing in bittorent, most of the movies i like, i watched them already before they come in pirate streets software, almost what i need tv shows, Naruto, smallville season 7;;;;;;;; give a shot for bittorent limewire for me is only good for mp3s
