the U360 is an awesome jack of all trades stick. If you are doing a Mame machine and want to be able to play more games better; like 49-way, analog, etc. then the U360 is great for that. Plus, with the configurable maps you potentially gain some precision that would normally come with a physical restrictor. (or maybe not depending on how you play)
If you really want a 4-way to 8-way (automatic) switchable, then the servo stick is a great option.
Kinda comes down to how what is more important to you.
