Overall feelings meh, some backlight leagage all around (not very obvious leaks with clear lines, but dark content looks very "cloudy" unless brightness is at 0%, I actually prefer the IPS glow in my U2312HM to this), and without NCP settings, which of course won't work in my most played game...
How so? HTC 8x has much shittier camera, no HAAC microphone, worse GPU, no memory card ability, and battery lasts only half the time of Lumia 720. Oh yeah and the clearback IPS is better quality, you can even see it clearly in the sun, use with gloves and even in low lighting the black levels...
