I like them both, but man.. I do like Megaman a bit more. Least one of the recent games, Megaman ZX I believe, drew some inspiration from the Metroid games....

What do you guys think?

I haven't played Megaman, nor have I played any Metroid game more than like once, but I personally like Samus better.

Samus does happen to have sexiness... I see none in megaman.

EDIT: Samus does happen to have ALOT of sexiness...

I like Megaman and I despise Samus in brawl, but their games are very similar. They are both platformer games with the ability to get more abilities and a shooting aspect to it. Megaman games in my opinion are generally harder in the platforming area. Metroid has a more scarier (scarier than megaman) aspect to it.
