I’m just so much more comfortable with SA1.
SA3 can do everything SA1 does better (except anti-air) you are intentionally handicaping yourself by using SA1 however I will say unless your planning on going to tourneys it probably won’t matter to much.
cant link sa1 off both of his overheads (i think), plus some of his links/cancels will make sa1 whiff at max range. ie low foward super. and he gets more ex meter usage cuz of 3 meter bars.
