Dragon Ball Z of course is the best amongst these three.
Was GOAT that set the stage for anime in general. At least until Cell saga it was great, IMO is became shit after Cell saga.
One piece actually fell off after timeskip. So it's the worst.
Naruto Shippuden was great until pain arc. But after pain arc, with the exception of Madara as the sole positive, it was shit.
So, DBZ > Naruto (shippuden) > One Piece (post TS) >>>>>>>>>>>>>>>>>>>>> DBS (just to put it there, DBS is amongst the worst anime I've ever seen in my life)
