Sanji Pu is really the best one in Wano, the most logical one, with the most build up etc. I don't like it either but other are so lame
Luffy PU makes perfect sense, he TRAINED Ryou, and Acoc has the same principles and logic as Ryou, but luffy only learn It after kaido showed to him several times.
Kid and lawa PU also make sense, since they can be TRAINED offscreen and we dont follow them as our protagonists.
Enma for zoro also was explained.
You have ALL the right to dont like It...
But the fun thing is literally EVERY Pu in wano ia far better than in Ennies lobby. Where was protagonists doing It, without training, NOTHING.
