Which phone is better?

[AVDADDY]

I can't understand why you feel the need to change. The iPhone 5 is not that much of an improvement over what you already have. As to the lumia 920... are you kidding? Even dedicated Windows users like myself are steering clear of Windows phones in favor of Android. If you must upgrade, you will be happier with the new iPhone. You can transfer your apps & get up & going very quickly because you already understand the Apple operating system. Changing to a Windows phone will result in a steeper learning curve, you will have to buy & learn new apps, and there is no guarantee that Windows will have Apps that are equivalent to the Apps you're using now
