depends on what you like... the J-sticks are very good sticks....
I have a ball top J-stick on 1 of my joystick now...
a couple of things that I noticed....
there are 4 screws that you need to screw tight to lock the template... you'll need to screw them tight... when I play SF, after about 20 min of playing.... if the screws are loose... the template will rotate by itself... (maybe cos I play too hard... heee hee...)
another thing about it that I didn't like too much is that the 4 main direction has a shorter distance than the diagonals....
the template is like a square... so... go up travels faster.... going diagonal is longer....
its not a big deal.... but needs to get used to....
cos I was playing 8 way games and when I go up... I sometimes ended in a diagonal....
out of all the joysticks.... I still like competition with heavy spring the best..... (just me personal preference...)
but Super, Competition, and the J_stick are ALL VERY GOOD sticks....
hope it helps...
ps: but the construction, design wise... I think J-stick is the best... its smaller and nice....
