Honestly...I just can't vote between the two of 'em.

Here's why...depending on what style you like...you just can't split 'em apple to apple.

Juan Manuel Marquez. JMM is supreme as a counter puncher. He's a smooth tapestry weaver through & through that has just begun to stand his ground for the fan's sake...which I truely believe is a gotdam mistake. Let his brother do that shit. Juan has shown his metal by defeating the HOF'er Marco Antonio Barrera, getting robbed against Chris John in Indo, drawing after 3 drops with Pacquiao, & outboxing the majority of all comers...quite impressively. The man's underratted, IWO, which brings me to:

Rafael Marqeuz. Heavy handed, explosive, skilled, & in the end...something of a fan favorite. Not exactly my cup of tea, as I favor the smoothness of the other bruvah from the same muvah, but I have always dug on the gent period.

Both are great in their own rights...so it's hard to pick one who is superior. If you could mix & mash 'em up...then you'd have the perfect boxer.
