Chocolatito impresses me just as much as Kid Chocolate did, in both an eye-test sense and an achievements one; but Kid Chocolate was much bigger. It's a flyweight to a super-feather/lightweight. We also saw Kid Chocolate fight on near even terms with one of the literal greatest fighters ever; Canzoneri. We never saw something like that from Chocolatito. Kid would win based on size.
This fight wouldn't even be fair honestly. One fighter is a career 105-115lber while the other has fought at 126-135lbs.
