Post [Q] 3M vs UV adhesive

Looking at the two types of adhesives, 3M is a sticker that you apply, not as strong and UV bonding adhesive,you apply to the screen and cure with light

Is there any benefit to using UV curing adhesive other then a stronger hold? I like the comfort of being able to replace my digitizer without damaging my LCD if I were to damage my phone but I am having trouble balancing the pro's and con's of each method

I also notice that UV adhesive is an increasingly more popular option, why is this?
