If you don't play 4 way games, then stick with the Sanwa. I like the feel of the Omni2, mainly the click of the microswitches. Now don't get me wrong the u360 is still a great product and I probably should have stuck with it, but figured I'd be able to sell it easily. The lack of the click was what got to me, but I'm sure I would have gotten used to it.
u360 was my first stick, but I never routed out my wood, so I then ordered the longer shaft. The throw was too long with it. If I don't sell it, I'll put the normal shaft back on and put it into a future cabinet.
