Pink Floyd.
One of the most epic turn of events ever, seeing Rush get knocked out. (Not that I was happy, but it certainly was unexpected.)
For me PF and PT are very, very close, but it goes to Floyd. It just has too, I really wouldn't be able to forgive myself.
I also support the archiving of the final round (and the wrap up thread). We should do this every year, and then compare DTF's tastes from year to year.
