Really, really happy with the iCarez ones I've got. They're edge to edge, with only a cutout for the speaker. With a case, you can barely tell there's anything there. The edges of the screen protector are also rounded so they don't feel sharp to the touch.

This brand sells a few different packages for the iPhoneX, but this particular one includes two screen protectors, and a plastic tray for perfect application. Every screen protector should come with an application tray like this, I got a flawless install on my first try.

Only $10.

You should try these. They come with a plastic frame you put around your phone that perfectly aligns the screen protector. I got a perfect install pretty easily on the first try. These go edge to edge, so they're much harder to notice than most.
