Scott could not cross the mountain ash in 5B when he went to rescue Lydia.

I think there really is no difference, all alpha statuses from the beginning come from true alphas. Only will allow you to get the alpha range. And if Scott could cross a barrier of mountain ash was because the ash also works with will (that said deaton to stiles in season 2) at power level I see even derek stronger as beta than scott as alpha (he fights with Two bersherkers being young and destroying one separating the head, and scott already had difficulties to fight with one)
