Which one is better...
According to display mate and toms hardware, the iPhone X
From Displaymate
Overall rating grade: IPX is A+, S8 is A+, Note8 is A+
I think displaymate is very good at the techniques but they are crap at presenting/reporting info
When S8 came out they went and say "best display in smartphone"
When Note 8 came out they went and say "best display in smartphone"
When IPX came out they went and say "best display in smartphone"
So are all of them are "best display in smartphone" since all of them got A+? At least give a point rating for finer comparison.
