I can't find the post that made me decide against the U360, but it had something to do with them being analog controls when most arcade games are made for digital controls, and the controls not sending the commands at the same precise instant that an actual competition joystick might have.
I'm not sure, myself, but having done business with ultimarc in the past and knowing that andy is a great guy and it's a cool company, I still had to go with traditional Happ joysticks because my favorite genre of game in the arcade happens to be 2-D fighter.
I'll look for that post I'm referring to a bit more:
here's part:
"My only complaints with the stick are how soft the movement is (several people have commented not liking it) and how easily the bat handle gets loose. The throw of the stick is longer than the Happ Competition sticks, but I don't find it to be a problem. I saw that Andy sells stiffer springs for the stick, but I can't justify spending $14 on shipping for a $5 spring so I can't say how much they improve the stick's softness. Has anyone else tried it? I also just noticed something on Andy's site about the stick having a screwdriver notch at the base for tightening the handle which I will have to try to solve the loosening issue.
So, would I purchase the stick again? Yes. I am considering getting another one for player 2, but will not do so until I can confirm whether the stiffer spring improves the softness of the stick. I prefer a bit more resistence than the stick currently provides."

Anyway, if I WASN'T a big fighting game fan, I'd have definitely gone with the U360 setup, but, I like to practice fighting games a lot and learning on non-standard controls might cost me valuable milliseconds in the real arcade. If that's not important to you, the U360 replaces the need for a plethora of controls, I've heard
