I would use hinata, because optimally you'll want to have at least one control on your team.

Not so sure of what you mean by wasting because her mystery makes her a very good tank especially when you are facing a lightning main with lightning shield - which has a critical hit bonus that allow them to defeat at least one of your ninjas with a single mystery as long as their power is not too low- you can dodge all of his attacks.

is 3 star naruto better?
isn't this question the same as the first?
or if you mean better than 1 or 2 stared naruto, yes.

He uses shuriken jutsu if there are two or more clones present, if not he will use a normal rasengan

hinata and 3 star naruto are both good, you can put both of them on your team,
or if you only wish to use one of them, i would suggest hinata

Thanks, then I think I will use hinata in my main team. Yea, lightning main can do a lot of dmg and hinata can dodge it all. I would use naruto as well, but you need at leas 3 clones to use rasen shuriken what is really hard couse in first round most of clones are mostly gone.
