Great Khali Vs El Gigante

Who do you think was better?

I'm going to have to go with Khali, because he at least had some decent matches with Cena and Triple H (Summer Slam 2008 in particular was nothing short of a miracle)

I don't know if Gigante ever had a good match aside from his mythical *** outing with Ric Flair (which may not even have happened)

Yeah Khali at least knew the basic mechanics of working a match and could mostly pull them off.  Gigante's deal was mostly just to stand there and occasionally choke people.  Khali wins by a landslide.
