Should i get iPhone or windows phone and why?

I'm currently on android and i really like it but i like changing os whenever i upgrade. So should i get ios or windows phone and why?

Go with the iphone. My friend currently has a windows phone and it has many flaws. Their is a bug on it where it opens the internet every ten seconds.

Probably windows phone because the cameras are the best and they have really good battery life

IPhone easily.

Better hardware, much more apps, performance, etc

I'd say iPhone. Windows is a great OS, but the lack of apps makes it really boring.
