I don't want to get into the arguing here , but just wanted to say that I voted for Shareaza and Limewire. I have both, and have tried most of the clients, but these two were the best on my machine. Although I think I like Shareaza the best. Limewire has a lot of files on search, but downloads waaaay too slow for me. Shareaza has tons of files on search, and downloads the quickest for me.

BTW, I HATE spyware/adware. Thinking of ditching Limewire just for that.
