I've had both. I loved my droid for a long time. Never had any issues with it. Dropped it in water and down a flight of stairs and the thing still worked. But I love the wider diversity on google play than the App Store on iPhone. But I bought an iPhone 5 in February, and I don't have any issues with it. I love it actually, but the battery life stinks, and I haaaaaaaate iTunes. I wouldn't trade it for another droid.
Android, simply because you don't need annoying itune -_-, the phone is very easy to use and custumize, I've had an S2 since it came back and still works!!! Chargers don't break unlike iphone chargers, if you drop these phones it won't break cx. I've had an apple and tbh most useless phone ever, in my opinion its just a name brand nothing really unique about it. So if your brand crazy and want to fit in with others go for apple. If you want a phone that is easy to use and customizable choose Android. (Sorry for all the grammar nazis I can't spell for life) cx
iPhone 5s. I just got one a week ago and it's amazing. It's so fast, the pictures are so clear, it doesn't crash, and it's just amazing.
