The only thing that matters is whether the performance in AH matches the flight-test data.
All of this arguing about what should or shouldn't be based on how big the ailerons look in the game, whether the wing is clipped or not, etc., is all just a philosphical discussion. You can't guess the roll rate based on such things -- there are too many other things that matter. In the end, you have to look up what the real plane actually did in flight testing and have the in-game plane match that.
