Keeping screen size and resolution (variables) out of the equation, I'd prefer Samsung's SAMOLED+ over everything.

It uses about 50% less battery than IPS screen at the same brightness, and both are equally viewable under sunlight except the (S+) having deeper blacks and better saturation.

SLCD with TFT-back is king of brightness and sunlight performance, but they suffer from shorter viewing angles than IPS or AMOLED types, and bad black levels which also gives them bad colour reproductivity.

Now it is very difficult, even with my Pilot eyes, but I can actually spot the "pixel jag" on the Galaxy Note...which is caused by the Pentile layout. Like said before, they just knock off one subpixel and share a neighbouring one, which saves battery but causes these "unsightly" jagging. Now I'm not sure what I would rather prefer, the Note's display or a qHD SAMOLED+ display?
