I would say Android more freedom.

android cause it's open source

Android, because it is less lame than the rest

i prefer windowsphone, well it's cool that it had its own livetile on the home screen, you can also edit the size of the tile. Its one of a kind here ^^ better than any other phone i had before

android is the nr 1

It's funny, I will probably never get neither of them

Android

ios better because of better games and added functionality with jailbreak.

No wonder why android is the winner,
very easy to handle,open source,supported by a lot of manufactures,a lot of applications either free or cracked,easy&fast to root rather than ios

I will Vote for IOS


Reasons:

1- User friendliness: can't explain it, it's all so well organized, no confusion, if I want to do something I do it in a matter of seconds with no lagging, no waiting, no buffering, no searching.

2- Stability: It's 3 years now ( iphone 4 and iphone 4s) and NOT ONCE my iPhone crashed. Need I say more? I'm sure I'm not the only case.

3- App store: You find everything there and what you find there WORKS 100% on your iPhone. Perfect fit on screen, perfect usability, perfect compatibility. Infinite number of apps available and quality and security is always at it's best.
You don't need to check apps, Apple does that for you. You just download and install them.

4- Materials: I had time to unmount a friends iPhone and my friends, not only the exterior which is gorilla glass, but also the interior is just an engineering masterpiece, from the antenna located around the phone, to the location of all silicon pieces. You can see it's high quality.

5- Speed: Last but not least, in terms of speed I never suffer any kind of lagging, especially swiping through pages on my homescreen on the iPhone, I don't know why but on my friends Galaxy S2 I have the impression that the swiping is taking that 1 microsecond to much to get started that really feels annoying coming from an iPhone experience. Same goes for opening folders. I seem to see a small lag if compared to my iPhone. Sorry if I can't explain better this one. It's just a "feeling".
