actual sanwa joystick and buttons on TE sticks. they are much higher quality. If you feel like it, or want to learn how, you can always get a fightstick and mod it with sanwa parts yourself. doesn't require any soldering or anything like that, just opening it up and replacing parts.
also the TE sticks are bigger and heavier, which is closer to the actual arcade cabinet feel.
is the te stick worth it compared to the regular one? it's pretty expensive, but i'll bite if it's worth the extra 80$
and i don't know anything about modding a fightstick, is it easy?
