Hi, new to the forums but just wanted to pop in and give my (long) opinion. Don't know if the OP is still vacillating between the two but here's my experience. I recently wanted to buy a 10" tablet and nothing in Android appealed to me, especially as Google seems to be very reticent about releasing an updated Nexus 10. I have a Note II and honestly as long as Samsung doesn't do anything unforgivable to the Note series I'll probably remain a Note user exclusively when it come to phones.
I splurged and just got the iPad Air and here's my experience. Google instead of encentivizing devs to create better optimized apps for tablets instead decided to do away with the tablet UI for a more phablet look. But I don't want a phablet UI in a 10" tablet. It works fine for the Nexus 7 (which I own) but I still think Google's approaching the tablet optimized app problem from the back end. On the other hand, iOS have beautifully optimized and generally better polished apps BUT their system UI is also just a scaled up version of their phone UI. Also I've had more random crashes (mostly in browser apps) than I've had using my months old Nexus 7. Low memory warnings and Safari and Dolphin crashes happen a frustratingly large number of times daily.
Also I forgot how criminally bad iTunes is to use or rather the iTunes store. In the one week I've been using it, I've had iTunes crash up 7 times in an hour. It is horribly bloated. I think the first time it hit me how little control I had was when I wanted to save a picture from online and it downloaded into camera roll, which is a horrible place to have downloaded pics interspersed with your own personal pics. No way to change directory folder. I am an artist. The second thing I did after setting up my iPad was to transfer some of my artwork onto the iPad. These are files that have been painstakingly organized and filed. I file my artwork according to the project name so it's easier to find. Except when I go into the photos app, none of my work is categorized by title and there's no way to change how it's sorted because Apple doesn't even bother to give you the option. Online, every reviewer was touting how easy and simple this makes organizing but how about the people who actually take the time to organize their crap? Apple doesn't cater to people who know and prefer a different system of doing things. My 1500+ files are now categorized into random "moments" some with a date of 2005 to 2009 even though I created the files early this year and they were modified as late as last month.
TL;DR
Apple is a beautiful OS designed to meet the needs of people who don't want to necessarily take the time to do certain things themselves. I think if I had never left iOS I wouldn't mind nearly as much because I wouldn't know the freedom available to me on other OS but as someone coming from a more open OS, iOS is positively stifling. This a view point you may come to share depending on how you use Android. The thing is, even if the manufacturer doesn't intend for you to do certain things with your phone as long as the capability is there, then its possible to do them anyway on Android, many times without root. On iOS, if Apple doesn't want you doing it that way then you're stuck unless you jailbreak and even then....
I ended up keeping the iPad for one reason. I do a lot of business, professional and personal, in Japanese and that is where Android is strangely lacking. The best keyboard on the OS doesn't support it and pretends the language is non-existent and the alternative offered by Google is piss poor in comparison. Know the limitations of each. I feel foolish having spent so much money on a device that lets me do so little of my own choosing but all it took was one little thing that it does better than Android, that happens to be important to me, and I decided to keep it.
