UFC's Biggest Draw?...currently

His fight at UFC 40 was the highest rated show ever.

Correction: It was the highest rated show since Zuffa took over.

I think Liddell has become a pretty big draw. Not as big as Ken, but perhaps bigger than Tito, probably because of his KO over Tito.

Shamrock is tops... followed in no particular order by Couture, Liddell and Ortiz.
