Migrating to windows phone...

Hey guys i badly need advice :/, my galaxy nexus's screen has broken and i'm in a market for a new phone. I was thinking galaxy note 2 but price is awfully high, HTC one x is very temping but i'm not sure it's battery is better than my GNex's and Galaxy s3 here is marginally cheaper than note -_-, so HTC 8x came to mind as it appeared really beautiful when i saw it at local store. I have never, however used any windos phone product, that was the first model i ever held in hand, and while it seemed fine, i'm not really sure what would i lose or gain by crossing from Android (been using it for a year and half) to windows phone, HTC 8x generally. I would really appreciate advices from people who have used windows phone AND android, especially late versions of both, as i'm not sure about app selection, games, game performance, internet and most general things smartphones are for, i'm not in the U.S. so i don't care about LTE and similiar stuff...Tnx in advace :)
