I bought UPDF a couple of months ago. Didn't get rid of Adobe right away just in case. I haven't found anything I need to do that UPDF doesn't do. I'm not a heavy user. Mostly just creating PDFs from Word or other apps. UPDF is plenty good enough for my needs and I'm happy to finally ditch the monthly payment. Like some others have said, the UX isn't as smooth as I would like, but the more I use it, the less of a problem that will be.
