Oh my god thats SO not the question.
The question is do you want the improved screen of the Lumia 920, the Nokia Music app (great app btw, like a mix between pandora and spotify of sorts, with offline play), downloadable maps with turn-by-turn navigation, a lockbutton at a reasonable position (thats my taste, I never understood the concept of a lockkey on top of the device), a solid build that really has that quality and reassuring solid feel, wireless charging (this is a godsent tbh), etcetera.
Also, Nokia are good at updating their phones. HTC has iirc a bad trackrecord.
Or do you want Beatz audio.
Personally I just looked at the devices and instantly decided on the 920, because I cant stand that design on the 8x myself. I really think its hideous. But thats personal taste, for sure.
Id say if you want a WP8 phone get either the 920 or the Samsung Ativ S. From reviews Ive read, they seem to be the clear choices for an upper-shelf WP8 device right now.
And Id say, coming from the SGS3, that the build quality of the 920 and the fact that its not an AMOLED screen makes it win out over the Ativ S (you can have a white background on your homescreen/etc without worrying that your phone is using 120% more battery because of it, which for me is quite a good thing). And since the Ativ S uses the same screen as SGS3, I can say from my own experience that the Nokia screen wins that battle.
