Who gets more credit for a win over Hatton. Floyd or Pac?

Lets say Pac were to beat Hatton is the same fashion Floyd did, or even better. Who should receive more credit for the win. Prior to Floyd facing Hatton, Hatton was the undefeated LWW champ of the world. Hatton then moved up to 147 and had a poor showing against Collazo (a fight in which many people feel Collazo won). He then went back down to 140 to UD Urango and KO'd Castillo. In his very next fight, he moved back up to 147 to face Floyd, and lost via TKO. Hatton went on to have 1 more fight against Lazcano with his previous trainer before dumping him for Floyd mayweather Sr. Since aquiring Floyd Sr as his new trainer, Hatton has had only 1 fight against Paulie Malignagg in a fight where many people feel that Hatton's skills have improved. Hatton won via stoppage. Hatton is now scheduled to fight Pacman in his comeback Mega Fight back at his most dominate weight-class 140. At this point, Floyd Sr has had ample time to get Hatton ready, and hone Hatton's skills that were missing with his prior trainer. From the training vids, it shows that Hatton has developed better defense, punching skills, and speed. Many feel that this version of Hatton will be the best that he's ever been. So my question is: Who will have faced the better version of Hatton, and who will/should recieve more credit for a win over him? Was Hatton ruined after the Mayweather fight, or has he ressurected into a completely new and improved fighter? Vote!
