Ok, CM's gotten a definite upgrade due to scaling above Quasar who scales to 4-B Phoenix Force hosts, who are generally stronger than Thor, which is better than before because we didn't know where she was in 4-B.
So, really, her Binary form is definitley above the 386 Kilofoe standard. Problem for her, IM is pretty much as well based on the fact his Model 51 is comparable, if not superior, to all his old suits. One of those suits can beat down the Avengers that included She-Hulk, one of his Hulkbusters can briefly content with WB Hulk (1 Megafoe), and another can destory that aforementioned Hulkbuster. Honestly, I don't see any real advantage AP/Dura between the two of them. Any difference would be minimal in the grand scheme of things.
However, CM really loses out here for a number of reasons:
1. While CM can absorb energy blasts, IM has created a blast that she
couldn't absorb. TBF to CM, she knows about this. But it's still an advantage to IM that he can actually attack her with energy blasts but she can't becasue, IM will just absorb it.
2. Even further than that, IM just has more of arsenal. He got missles, sonics and zero point energy to get a leg up.
3. IM has better defense. His energy absoption means that CM is left trying to punch his lights out. When it comes to the physical brawl he has regen, his armor has regen and he has energy shields to back that up. So, he take the hits via dura lone, and regen most of the damage he takes.
When it comes down to it, IM just brings more to the table. He neturilizes CM's major offense and defense and even if he didn't he as the advantage in a physical brawl due to the fact that he could reasonably outlast her. Then you add in little things like his sonics and zero point energy and it's pretty clear that IM would be in the best position to control and win this fight.
