Randy Couture dominating Tim Sylvia for 5 rounds to become the HW champ at 43 or Matt Serra knocking out GSP in round 1?
For me, Couture impresses me more. Only because Serra caught GSP and I'm not sure if he could do it again. I think that Couture could beat Tim 6 out of 10 times (maybe more). I'm not taking away anything from Serra because that was an awesome performance, but I think that GSP could beat Serra 8 or 9 out of 10 times.
So, what impresses you more? Just curious to get some responses.
