I enjoy playing Guilty Gear X (PC) on my cab. There are actually quite a few PC Games that play well on a cab. There are a few threads floating in software and everything else that name quite a few.
Hyper Bowl and Hamsterball are fun trackball games with good replay value especially if you are in a party environment.
I would guess playability also depends on the controls on your cab and the genre of games that you like.
