I am using Lumia 920 from past 5 months, perfect phone with good voice reception, XBox games, wireless charging and Camera quality ( most important features). Perfect Win8 OS with refreshing metro UI and active tiles.
Earlier I was using Nexus 4 phone, even that phone is perfect but only issue I can see in Nexus 4 is its bad build quality and same iPhone inspired android UI, once it got slipped from my pocket and screen got broooom it was a very painful experience as it cost me 5400Rs for new display.
Lumia 920 phone build quality is perfect ( as it brand Name). Lot of people have app issue but I cant see any app issue I can get all the apps which I need in app store and that also free of cost. Camera quality of 920 is well known to whole world so I will not say anything on that, but XBOX is ultimate thing you can play lots of free/trail games on your phone and you will get almost similar PC like experience.
Overall I am happy with my Lumia 920, only SAD part I have is the cost. I bought it in 36800rs and now it is 31600rs :(
