Unregistered had the best point... it's hard to say until you use them... I personally enjoy limewire and I don't think I'm about to switch to another client... however depending on your needs and you configuration and knowledge you may need a different client... bottom line download one and try it... if you can't understand it or don't like try another... and remember some problems are because of the network and not the client application so if you notice that downloads are slow on one particular client that just means that you got a bad host.... it isn't the clients fault...
