Both of these guys have great standup similar styles and body frames. Yves one of the all time best in the Light weight division. Melvin a strong up and commer with some impresive kickboxing belts to back him up.
Gotta give it to Yves then simply because Melvin hasn't gotten up to that level yet. Maybe in a year or two we can seriously talk about him being a top 10 LW though
