One Piece wins
While Fishman island was poor the adventure under the sea was fun and the world building at the end helps a lot.
Punk hazard was ok and it brought back Law and Smoker and Vergo was cool
Dressrosa was fantastic the building of the grand fleet, the best villain in the series, sabo returns, gear 4, god usopp and his observation haki unlocking, kyros was cool, fujitora was cool, it was a little longa nd rebecca sucked but the cons come nowhere near beating the pros.
Zou was awesome, the world building again, raizo is safe
Whole Cake had its problems but again the pros far outweight the cons, sanji's expanded backstory was great, katakuri provided the best fight since Lucci, snakeman, jinbe ditching big mom at the tea party, pudding was awesome, sulong carrot, the escape was a little long but who cares
Wano is easily the best arc post time skip, i have no complaints about it.
as for Naruto
Kazekage Rescue was good.
Sai and Sasuke arc was ok, i hate Sai so him being a big part of this arc just annoyed me, naruto's three tailed form against oro was great though and sasuke's still a dick.
Hidan and Kakuzu awesome arc, no complaints.
As someone who hates sasuke the next part of the story were he puts together Taka/Hebi was unbelievably boring for me, i just did not care the final fight against Deidara was pretty good though.
Jiraiya vs. Pain was awesome
Sasuke vs. Itachi was awesome but then we get the retcon where Itachi goes from epic villain to "sympathetic" anti-hero despite the fact in order to wipe out a clan you have to kill children and babies who know nothing of the hatred and if that excuse is good enough for sasuke then why not those kids and what about his mother, she's not an uchiha is she? she's only one by marriage right? or are the uchiha clan all commiting incest? it was stupid and not thought through and it ruined Itachi for me.
Pain's assault on Konoha was phenomenal and should have been the second last arc of the story, the end with the mass resurrection sucked though and was the beginning of the end.
Kage summit was good, should have just had the naruto vs sasuke final showdown here , write in Kisame, Zetsu and Tobi's defeats and viola you can end the manga on a high but alas that didnt happen instead we get the...
Shinobi war countdown, naruto taming Kurama is great but holy crap is his birth flashback garbage. there is no way that Obito could gain enough power to fight on an even playing field with Minato in a year, thats ridiculous.
Every decision Minato makes is the wrong one, it like teh scene with Carmen Electra in scary movie where she' in front of two signs where one points to life and the other to death and she chooses death except Minato does this about 5 times.
And despite all his stupidity he actually can survive the encounter but instead chooses to abandon his responsibility as a parent and leave his child an orphan with a monster trapped inside him, based on this flashback how anyone appointed him hokage i'll never know.
If it had been Madara then fine but he was trapped in that cave and couldn't leave.
What do i say about the war, there was way too much focus on too many characters i did not give a crap about like, thanks to TNM recent reviews i can actually remember them lol but the silver and gold brothers, the dead kage's, hanzo, the samurai dude, who cares, why are we wasting so much time on them, its boring.
Then Kabuto and Obito, both the men who started this damn war are talk no jutsu'd into changing sides......wtf are you kidding me, sure cause usa could talk no jutsu hitler and hirohito during WW2, thats just bloody ridiculous.
Naruto becomes a child of prophecy completely derailing the whole point of the stuff from part one with Neji.
Madara is so overpowered that he needed a deus ex machina to defeat him then he was replaced with some random nobody who was mentioned 10 chapters ago with a specific weakness for Naruto and Sasuke to exploit in order to win, after all that build up, all that investment Madar was just thrown away for some random villain wrote in at the last minute, utter nonsense.
One piece has its problems but Naruto isnt even close to ever beating it and it never will be.
