They both work well as cool pulp characters. The issue is that MOTU has shockingly little good fiction and it's never transcended the toy business the way Transformers and G.I. Joe did. A lot of fans of the Hama comics never touched the figures and don't even necessarily care about the cartoon. Transformers is an actual IP juggernaut: the toys barely matter.
I think some of the more recent DC comics and Revolution were pretty good, but MOTU never hit escape velocity. So Skeletor remains wacky 1980s meme-fuel.
