The way I see it is like this, the reason why MMA is more tense and you can say more exciting is because it's basically a street fight with some rules involved I mean how many of us haven't been a street scrap?
So when you sit and watch a MMA your tense and it's almost like watching a street fight.....

I personally have seen both MMA such as Pride and K-1 and UFC....
I think they are all good and entertaining but IMO it doesn't come close to a good boxing fight.....

I was ringside for Marquez-Vasquez and I just saw Couture-Sylva (Thanks Heavy D )
and I can honestly tell you it doesn't compare the kind of blows and the way Marquez & Vasquez traded shots! was insane....
Coture-Sylva IMO was like Cotto-Urkal.......

Miranda-Green started off slow but picked up the pace. They traded knockdowns and got to work....

It all boils down to what your into or what your looking for.
