I just don't like Apple at all, it's overpriced and they bring all the features like they are world changing while they are not. I think Apple is no longer as innovative as they were called before. But the most I dislike the fact that their eco-system is so closed, I love the fact that I can do whatever I want with my phone and tablet without being restricted. For me that's a really important thing, I don't want to be jailed by anyone.
Besides that, I would say that objectively you get more bang for your buck on Android. 64-bit is not something you will notice with real-world usage, maybe benchmarks will show some speed increase but it's mainly because it can now allocate more memory, that's what I understand.
However the news is now full of reports that say Android will also support 64-bit soon, so it's not even a novelty anymore, I guess it was already in the pipeline and just a logic step forward.
The numbers are already clear, Apple is not as dominant as it was anymore and I think in three years their market shares will be nowhere close to what they are now. Android is open, many big brands contribute to it, and I think we'll see it in more devices than just phones, tablets and TVs. I rather see Android with their open eco-system do that then any other closed OS.
