There is no best brand for tablets, just as there isn't one for smartphones.
I guess this really depends on what you're looking for/your budget. Apple and Samsung are usually the best in both segments (tablets and smartphones). You could try Ipad Air 2 or Samsung Galaxy Tab S.
I agree but they're overprice. A cheaper one will do they job just as good, just don't go too cheap. Op, why don't you give us your budget and maybe people can give you better recommendations based on that.
