When to pick Battlefield or FD?

[Lampwick]

Hey fellas,

Recently I've been playing a lot of quickplay. I normally don't pay much thought to the stage, but I'm curious as to when to pick which stage. What kind of characters benefit or are hurt by the platforms? What about the flat stage? I've recently been playing a lot of Greninja but just can't decide which is better!

For greninja i would think platforms are better for him given the playstyle. Also gives him some room to camp projectiles
