FWIW, I was waiting for the "perfect" E2E glass screen protector to come out. I ordered the Jelly Comb E2E to use temporarily and ended up using it since shortly after the iPhone 7 launch. I ended up ordering the Tech Armor Corning 2 non-E2E last week and love it. The main problems with the Jelly Comb was that auto-dim hardly worked(wrong sensor cutouts), had lifting on the corners and the oleophobic coating was non-existent. The Tech Armor is much thinner and sat nicely on the screen. The oleophobic coating is also MUCH better. I haven't ran into any issues with dust collecting along the edges of the screen either.
I would say I wouldn't recommend a non-E2E if you aren't using a case but with my case, I never hit the edge of the protector with my fingers.
