I have shot the USP extensively, in all calibers. I used to own a Glock 21, sold it for a USP9 full size. I plan on getting a USP45 (full or compact, not sure yet) soon.
My thoughts? Whichever you like best. The USP is defintely superior in fit and finish, if you like I can make a specific list of things I like better about my USP versus my Glock 21. slide to frame fit and NO RATTLES are two great things about the USP. No squeaking of the recoil spring(s), the USP cocks silently. Things of that sort.
Both, IMO, are reliable and accurate guns that will not fail you when properly maintained (NO LEAD BULLETS). Pick the one you like and shoot best, the trigger and external safety are the main differentiating points.
USP also has real, steel sights and a steel recoil rod. I vote for the USP, but the Glock 21 is one of my favorites as well. I can tell you that I made a mistake by selling mine. I can definitely see myself getting another one, or maybe a Glock 30, down the road.
