Marquez is by far the more skilled, and I would say mentally tougher of the two, while Ortiz is younger/fresher, bigger, and stronger than JMM. Styles make fights, and for me I would say that for Manny, JMM is tougher and for Floyd, Ortiz is tougher. JMM has a great chin, is a crafty counter puncher, and "gets up" for Manny, meaning he fights at his best against Manny (kinda like Barrera did against Morales, Bowe against Holyfield, Holy against Tyson...etc.). Floyd is a slightly larger, faster, and slicker version of JMM, and this made Floyd's fight with him a blowout. Floyd doesn't have Manny's punch or all out offense, so it will take him longer to get Ortiz out of there than it would for Manny, since Ortiz would get caught and overwhelmed against a whirlwind like Manny. So just to clear it up, Ortiz is the easier fight for Manny, and JMM is the easier fight for Floyd.
