I think you cannot measure if someone is 'better' at a character.

Well, actually you can, but only until you got to the point where you would consider both players knowledgeable about the character, meaning they know pros, cons, frames, and move properties.

Then it's not really a "being better", it's more a "making better decisions". And this can be applied to every character.

Or better said ... it can be applied to every situation, so it's nothing character specific.
