They're all priced very similar. Does the armorite screen protector reduce touch sensitivity due to it's thickness?

I was also looking at the spigen screen protector but it only comes with 1 pack for the same price. Is it any better? They do also provide a bubble removal tool which ESR doesn't? Correct me if I'm wrong
