I'm about to download AIM onto my newly reformatted computer, but there are a few to chose from.

I hate ads. I love tabs and I don't like lots of pointless crap, which should I download? Main thing is, tabs and no ads.
AIM Pro - http://aimpro.premiumservices.aol.com/
AIM Triton - http://www.aim.com/get_aim/win/latest_win.adp?aolp=0
Or older version of AIM.
