4th. I used this to download 2 files, one large and one small, and i have to say, very impressive.
Its not a huge resource hog like some other clients (ABC, PTC) and is very easy to navigate for the average newbie or intermediate!
Clear screens to follow and auto-resume feature even when application is closed down and re-booted.
Gives a current list of torrent sites to download from which is also nice, not sure if its auto-matically updated or updated through version upgrades, non the less. A very seemingly stable client.
I would recommend it!
