ok... happs... have 3 types... (actually.. more...)
they are ultimate vertical, ultimate horizontal, and competition... push buttons...
I've tried all 3 types...
now... ultimate vertical... stay away... bad... bad....
(ok.... when you install it... its easier... cos the microswitch is vertical... so, you can leave it in tact.... but this is a 1 time thing.... so, no big deal... but the feel of this button is BAD... compare to the other 2...)
Ultimate horizontal... it looks like ultimate vertical on the outside, but the microswitch below is horizontally mounted... it looks very much like most arcade ones....
pretty good feel.....
competition buttons.... the look is a little different... the button top is convex (curve up).... some of the NeoGeo arcade uses these buttons....
these buttons are lighter in feel... and seems like shorter in throw.... (so.... in general... response will be a little better...)
--------------
if you want the look of real arcade... I think you should go with utlimate horizontal.... (assuming you're not into the minor Neogeo machines that uses competition buttons...)
if you want to max your high score in like "hyper olympics"... then you might want to give competition buttons a try....
ps: I'm using ultimate horizontal on my panel....
(if this makes any difference to you at all....

)
as always... above are mostly my personal opinions....
(or opinions shamlessly copied from other posts....

)
hope it helps....
