One X has the best overall screen quality according to most reviewers.
However Galaxy Note's AMOLED HD is no slouch either, quality wise it is
like 95 vs 90? Although I understand some people don't like over-
saturated colors, you really can't see the pixels unless you use a
magnifying glass or something. This is not Galaxy S2, it is Super Amoled
HD!
When the screen quality is very close, I rather have the extra screen
size. You really can't go wrong with either one, if you like huge screen
go with Note, otherwise One X is the best although I would wait two more
days and check out GS3.
I personally would not use anything other than Note-sized devices from
here on. If Apple makes a 5" device I am going back to iOS immediately
for the superior ecosystem. But Note's screen size was what pushed me to
the Android camp.
