He's a top 10 grappler of all time without a doubt. He's got more wins in the gi, but he's competed MUCH LESS without one. That said, he's never lost at his weight without the gi on, except for Rafael Mendes.
EDIT:
Seriously ya'll. If you have not seen the epic that is Cobrinha vs. Rafa Mendes for the ADCC 2009 Gold Medal at 65k, you are missing out on what is probably the best no-gi battle in history. It's definitely the most back-and-forth war in ADCC history.
What makes it so amazing is that they're rivals and it was both of their first times at ADCC. These guys throw everything but the kitchen sink at each other. Kimuras, heelhooks, reverse heelhooks, RNCs, calf crushers, anaconda chokes, darce chokes, sweeps, back-takes, good stand-up, the whole 9. It's everything a no-gi fight should be.
