Best glass screen protector fitment?

[Meltdownblitz]

I realize companies claim they are not able to cover the entire iPhone 6's screen without the glass lifting.

I have the Xtreme guard spartan glass right now but I feel that it doesn't cover enough of the screen although the cutouts are perfect. Also a huge dust/dirt catcher around the edges of the glass.

So what's the best option right now as far as fitment and thinnest goes?

Thanks.
