IMO Cody has the slightly better durability -- but it's arguable if it would be enough to matter. More willingness to mix in TDs and better cardio, too.
Marlon has the more diverse striking arsenal and is maybe a little more technical on average.
Both are fast and hit hard.
I guess I'd narrowly favor Moraes inside 1.5ish rounds by KO/TKO (it could just as easily go the other way), but once they get past that mark the fight swings decisively into Cody's favor IMO. I'd favor Cody overall IMO. More ways to win... but exceedingly little confidence.
