Should I buy a HTC one or an iphone 5?

My phone is almost a year old on a 3 year contract and i just can't stand it anymore. I'm thinking of buying it out and getting an HTC one or an iphone 5, but i don't know what to get. I know htc one is better in specs and pixels, but the iphone 5 has a better selection of exclusive games, which i like.part of the reason i don't like my phone now is because the google play store doesn't have most of the good games on the appstore. I really want a new phone to play games and stuff like that? What one should i get?
