Castillo was better hands down, you can't compare the level of competition Castillo has faced to the 90 garbage Hatton has faced, sorry, Castillo has names like Corrales, Mayweather, Casamayor, Lazcano, and more on his record, all Hatton has is Tzyu and Castillo himself, sorry history wise and greatness wise i'd say Castillo is way ahead of Hatton
