I think one of the big differences is the gap between the top(title fights) and bottom fighters in the ufc. I heard that some of the recent title fights(liddell v Sobral) liddell made over $200,000 campared to some of the lesser known fighters who made around $5,000. Although the ufc has IMO the best welterweights in the world their hevyweight division is a complete joke compared to the talent in the Pride heavyweights. Both organizations have their own strengths and weaknesses. Either way I can't for the Real Deal on the 21st, it's gonna be a great event and good for the sport.
