Allright, another match-up. Both have appeared once and both played a big role in that game (which is still freaking awesome btw). But who to vote?
Lynn is fast, very fast. Unlike Marth (who is a royal) she learned all of the sword skills by herself. That means her style is unlike people who just swing a sword around. Just look at her attack animation in the game and you'll see that she delivers quick, but lethal blows. She's fast and that's her best thing. When Lynn transforms, she's even stronger. And omg, she has a bow! Now that would be nice eh? Shooting clowns from a distance and slashing them when they get too close. And her critical attack kicks *** too, so no reason to be worried about a Final Smash.
Hector is slow. Dang it slow. But slow isn't always bad (Ganondorf <3 my true love). His strength is immense and (that's why he's nice too) he has an axe. We do not have an axe user yet. Swinging an axe can be just like swinging a sword except for that Hector will be slower then, let's just say, Link. Axes hit hard people, we all now that, so Hector will be a true powerhouse. When he transforms, he's also able to use swords.
This is not a battle of fanbase, but a battle of gameplay addition. And sword/bow combination appeals more to me than an axe/sword combination. Furthermore, Lynn is hot and fast. You would pick a slow fat guy over her? No offense to Hector, but Lynn just attracts me more than he does.
So I voted for Lynn.
