Leonard by far...No way in hell Tito could have ever beat Hearns let alone KO his ass..Tito's power has always been kinda overrated in my opinion..But its a fact Ray's power is not overrated..
Tito was the harder puncher, but Leonard was better overall, which helps in scoring stoppages. No way Leonard hit harder, but Leonard could crack.
Trinidad's left hook was P4P one of the hardest ever. He knocked guys silly. I agree with most so far, overall Leonard was far superior in almost everything else.
Thats because Leonard was the greater overall fighter than Trinidad. If Trinidad could hit Hearns he would beat him.
Tito had more power, and there's no real debate about it. However, the fact that Ray had power AND blinding handspeed on top of it, in a lot of cases made him more devestating. For instance, I don't think Vargas would have gone 12 with a prime Leonard. I think Ray woulda put Vargas on his back in about 8-9, due to the speed aspect. Put it this way, the gap in speed between them was greater than the gap in power. But for raw power, Tito was a bigger puncher.
SRL had more everything over Tito. Trinidad was very overrated, he didn't know how to box. Don't believe me? Watch Trinidad vs Wright.
