Confirmed that PenTile is crap. I came from a OG Droid to Galaxy Nexus and was horrible not impressed by the PenTile screen. It is really noticeable when using low brightness.
Not all pentiles are equal. I have no real complaints about the Galaxy S II screen. (OK - a bit more maximum brightness and a slightly more natural default colour calibration...)
I often wish the minimum brightness on the SGS2 screen were lower. Most of the time I run at the lowest setting, and if I use the phone in a dimly-lit room I further darken it with Screen Filter (to about 35%) to avoid overloading my eyes... Very rarely do I need to use the maximum brightness, except outside in bright sunlight.
