Ororo vs Johnny Storm. Standard rules
Storm takes it, aswhile they both need just need to get one move off, Storm's lightning will hit Johnny likely before he can get off a fireball or whatever.
Essentially a quick draw. I'm inclined to think that Storm takes a smaaaall majority just cause lightning moves faster than fire. But that's real world logic lol.

In an non-quick draw scenario, Storm should be able to deprive Johnny of oxygen to burn, but in this fight, yeah it is whoever goes first.
I'm sure Storm would use arctic winds to freeze Human Torch.
