After years of using the UV product you mentioned (whitestone dome) I settled on the practical plastic films. These are very cheap, you can get 2 or 3 at just $10, they avoid scratching mainly and the feel is not as good BUT cleaning up the screen after removing the protective UV glass is a nightmare, replacements cost $40 to $60 in case it breaks or dents. The plastic film doesn't really dent and it's much thinner and as far as my experience goes most cases are compatible with the plastic one, in contrast with the UV glass. Furthermore, the installation of the glass is not "for everyone", I am used to do precision work with my hands and the installation process is not something I would recommend to an inexperienced person: some glue is going to get outside while curing the screen with the UV lamp and it can infiltrate in your mic holes or in the small gap between the display and the frame. Last but not least, if you want to use the phone without a case with the glass you get a noticeable step on all 4 sides which is very uncomfortable especially if you use gestures. If you want to give it a try, is something you can live with and it has for sure benefits as far as feeling and protection. On the other hand, all the above issues remain. Sorry for the bad grammar and punctuation, I'm in a hurry. I hope my comment helps you decide for the best!
