I haven't played Mega Man Zero. I guess Zero might be cooler as far as narrative goes, especially if you're a teenage girl, but if you want to own s**t and feel like a total badass doing it, X with at least an arm upgrade is the way to do it.
The plot's pretty bad a** for Zero though. He gets resurrected and helps save a group of rebel reploids, eventually killing (a copy) of X. Also cutting s**t with a sword or a spear feels way cooler than shooting with a gun or other special power.
That and the game ends with this scene.
And I think we can all agree that any protagonist in a game that ends with a scene like that is a bad a** that most other protagonists can only dream of.
