Ran two clients through the afternoon, both downloading a single file. One was BitComet which I have been using for a while, and the other was ZipTorrent. The search feature in ZipTorrent was not working, but the area I looked at was memory usage. BitComet was using around 48meg, ZipTorrent peaked at 8.5meg. Runs in the tray, supports RSS, doesn’t look ugly … good enough reason to switch.
