To be honest, unless you have an existing investment in Android or Android apps, or have a specific need that Apple doesn't support, the iPads are better tablets. They are built better, work smoother, and have much better battery life over all. I am the lone hold out in my family with a Nexus 7 and a Galaxy Tab S2 (because the N7 is starting to get creaky)
The only issues I get from my family, who are uniformly Apple users, are that printing directly from apps doesn't work right (generally solveable by using the Brother print app), occasionally the bluetooth will glitch and cause the music player to start automatically, and Safari will crash under moderate load. Dolphin generally solves that latter issue, though I'm not sure how. Oh, and there are no obvious ways to block ads outside of the web browser. That's it - really. Otherwise, they love the things. We have upgraded through the iPad 2 to the iPad Air and now my wife is on an iPad Air 2.
Given Google's lack of interest in tablets and tablet software, the only thing keeping me on Android tablets is the fact that I own a lot of Android apps and games for them, and several reasonable firewall and privacy apps are available for it. Obviously, as an XDA member, I tend to prefer a higher level of control and modification of my devices, but if I were suggesting something for a non-technical user, I would point them at the new iPad 5. (unless they want to do art or technical work, then an iPad Pro 9.7")
