I havr used ipad air 2 wifi 128 gb for over quite long time but now my view is fully changed I think woth that big screen the iphone 6s plus is better iphone 6s plus has got more features with that same screen size though they have the same screen size and same price if of want to ugrade and a more larger screen you can ipad pro ipad air is between them which is totally waste of money though you can get that if you want to get a low price tablet.
