I used a S2 for couple of days , now I have a RAZR . I'm sure the GN will blow the RAZR out of the water cause the screen on the RAZR is the worse AMOLED I've seen being released in the last few months.
I own the Razr and the screen is great, having owned several smartphones. Also, I don't buy a phone solely based on the fact on the screen/display quality may be subjectively determined as the "best". Also, I just want to point out that your comment is not only an assumption (" I'm sure..."), but may be misleading to those who don't understand that the RAZR is the best phone available right now.
