Galaxy S II by Karla-Velarde (Dec, 2012)Is very simple to use when you get used to it, nice camera, very good HD screen quality, is the perfect size for those like me who think that we don't need a phone of the size of a tablet.
RAZR XT910 by Mike (May, 2012)The phone itself is very light yet seems to be tough and has a big screen, which I like.
screen resolution
Galaxy S II by GSM Arena (Apr, 2011)The images captured with the 8MP camera of the Galaxy S II are very good – low noise, plenty of fine detail and the color and contrast are good too.
RAZR XT910 by GSM Arena (Nov, 2011)If you put the RAZR and the Galaxy S II side by side and look at text (or something else with a lot of detail), the Galaxy S II actually looks a little sharper even though it has a lower ppi.

cpu speed
Galaxy S II by c|net (Sep, 2012)Though Qualcomm's chip has a slightly faster CPU, we didn't notice a huge difference in speed in everyday use, and in fact the AT&T and Sprint models felt just a touch more responsive.
RAZR XT910 by Alejandro-Aparicio (Jan, 2013)The processor could be better, but as someone else said the battery would drain sooner.
