Iphone 4s or new Windows phone?

I don't know which one is better what would you think?

Well I'd rather have an IPhone. But, I think the better one would probably be the windows phone

4S
Hate windows

I'm an iOS technical advisor for Apple and my cell phone is a Nokia Lumina 920 Windows 8 Phone… If that tells you anything lol.

I have the 4s, and both my mum and sister have windows phone, mine beats them in everything apart from screen strength as I just cracked mine: P
