ESR cuts into the screen with its black border. I wasted 5 protectors and some light bleed on the left and right. Spigen doesn't cut into screen area as it doesn't have a border but you'll see a rainbow like effect from sides. I am so frustrated with protectors this year and my ocd is getting out of control. I am gonna keep my esr on until the flolab privacy 3d whatever it's called comes. Although I have heard mixed reviews I found that it was superior on privacy version as compared to torras or esr but will see when it comes.
Below is a pic for 17 Pro version. All the "L's" on esr are covered by the border. All their versions 2z, 7x and 10x have the same issue.

EDIT: If you're solely looking about the installation then ESR (Ultra Fit) is miles better than spigen ez fit. It auto aligns and removes dust where Spigen is definitely gonna collect some dust particles which you have to clear out after applying.
