I downloaded Azureus months ago and i found it very hard to use as i was having problems with very slow downloads. I went back to LW and the downloads were normal speed again.

I was getting NAT errors when my firewall was off and my ratio was almost at 1. I couldn't figure it out so i gave up.

The specs for Bit Torrent Clients are more complicated as i found out in a support forum for Azureus.

So i guess Bit Torrent clients are good for people that know how to use them.
