I have a pair of X-arcade joysticks, as well as a pair of Happ Supers.  In my opinion, the Happ Supers are a better joystick.  I always seem to have problems hitting the diagonals with the X-arcades.  Is there a way to tweak them?
Also, I have the X-arcade buttons as well.  I have no complaints about these, they seem to perform just as well as Happ buttons, they a just a little more "clicky" which doesn't bother me.
