To the dude quoting Engadget: seriously? They're one of the more biased sites out there; getting better, but still not very objective. I read Engadget all the time, but I'm not dense enough to take whatever they say as smartphone Gospel.
Ignorance is bliss. Don't go near an iPhone 4S.
I don't care for the iPhone 4S's screen for two, major reasons: too small, and not OLED. It's a very nice screen,
for a 3.5" LCD. That said, 3.5" is too small to be usable, and I don't like the contrast ratios or the non-blacks on LCD screens (yes, even the IPS LCD made by LG for Apple). Apple's screen is basically a higher res OG Droid screen; both IPS LCD with a great colour gamut, but neither hold a candle to sAMOLED. It's like comparing an LCD HDTV to an LED HDTV; actually, it's almost exactly like that.
As for the "pixellation," it's non-existent in real life usage. Can I see pixels on my RAZR if I really try? Yes. Do I ever see them in regular usage? Not even close. The RAZR doesn't technically have the best screen out there, but there's no way you would know the difference in day to day usage. One thing to remember about tech blogs: they have several devices on them at all times. They're looking at the RAZR's screen right next to a SGSII; taking macro shots, running comparison videos, etc. They can then say, "Oh, I
do notice that slight blue tint you were talking about." If they didn't have the other phones for comparison, the negligible differences would become just that: negligible.
Bottom line: the RAZR has a beautiful screen. It's not the best out there, but the differences between it and the best screen will never rear their heads in normal usage. That and the iPhone 4S's screen is old tech; a very good example, but old nonetheless (kind of like how good carburetors were right when fuel injection was released).
