I can't believe Erik is actually younger than both of the brothers. I'm not that familiar with Rafael, but against JM, I think he'd lose. (Vote once for each opponent)
He was at his best 122-126, as good as Rafael is, Erik still a level higher than him. Erik beats him for sure. On JMM, tho, I go back and forth on this one, but I think I'll give the edge to Erik. He was almost unbeatable in his prime.
