Apple vs Android

The age old debate starts on Leakzone today! A simple one really, what do you think is the better mobile OS from a personal perspective, Apple or Android (any of the various forks)? I think now more than ever, I can see more people criss-crossing between the two systems which I think is a lot healthier than the usual 'this or that' attitude the 'net seemed to use to have. For me, I tried Android first (wayback when) but then I swapped myself back to iOS for a good few years, with one break in-between before heading back to iPhone. Now that my contract is coming to an end, I'm thinking of hopping back to Android again. It's a fun little life game.
What about you? Which ones the best for you?

Personally I use both quite regularly, and prefer the Apple ecosystem with how all their products seamlessly work together... it's pretty cool actually.
Having said that, strictly speaking about mobile OSs, Android is still superior when it comes to advanced functionality, with it being open source and more accommodating for power-user needs. I think it all comes down to how much of that added functionality you require on a day to day basis.
