I guess everybody is going to be different, mainly because it depends if they are just going for the Uprev on it's own, to benefit the throttle response and fuel savings, or for those going with a couple of mods or more etc.
Personally, I love the throttle response, I never noticed any fuel savings as my mpg went south!
The benefit of the remap for me was purely to allow the mods to be mapped.
Something I'd like would be multi maps.
