CMM > Corvus.
Corvus is definitely the best Cosmic champ and arguably the strongest champ in the game. Great damage, Partial immunities, brilliant utility, 25% AAR against tech, true strike and more.
This debate seem to center around Corvus, CMM and Hyperion. Regarding these three, Corvus is the only one with a definite limit which is his glaive charges. I'd say that Corvus takes the price when the content fits that limit, but beyond that limit CMM and Hyperion has to be regarded as more convenient due to lack of such limit. I believe CMM has something really unique which is massive damage while indestructible which also makes her more suicide friendly than Hyperion due to both the indestructible and the binary shrug off. That means that CMM's damage potential is higher or at least more convenient than Hyperion's since she more fittingly can make use of the massive damage boost from suicides.On the other hand, CMM really needs Fury to access her full potential. While Fury too is great, that synergy is another requirement which also is a kind of limit. As opposed to Hyperion who needs nothing more than his awakened ability. Conclusion:For limited content where Corvus can kill within his glaive range he is unmatched due to his massive and easily accessed damage combined with superb utility. However, the title as the best cosmic champion simply cannot involve such a limit when other contenders expand further.Hyperion shall be ennobled as the most agreeable and handy of the three as from the moment he is awakened he is at his finest with superb damage, great utility and no great limits in sight. But the title as the best cosmic champion has to apply to CMM. She is unique due to her indestructible. She is suicide friendly and when that applies plus her Fury synergy she reaches potential that goes beyond both Corvus and Hyperion.
I made a list of pros and cons I am familiar with regarding Corvus, CMM and Hyperion: Nice list. Giving Corvus Power control is a stretch as is the armor break
