Depends on your stick and if the gate can be swapped. I mod every one of my fightsticks as well as build them for retro arcade machines.
BTW.. square gates are the best.. maybe you should learn how to properly use a fightstick versus modding the gate? No knock.. just saying from experience. Also quality of components make a big difference.. sanwa all day.
Arcade cabinets dont use square gate unlike the basic home stick that use square gate. I played mvc 2 tekken 5 others with official cabinets using circle gate and square gate are not the best its for them new generation kid fighters though , im old school
