It had a lot of very good moments, Shanks giving the hat, Luffy meeting with Zoro next the arc with Buggy was average with some good moments, same with Usopp's arc, it was quite interesting with Kuro (I would like to see what happened to him after that arc) and finally we had Baratie arc, the flashback story about Sanji was good and you could already see there that it was different from other manga, the comparison and build up with Krieg and Gin situation, how Krieg betrayed Gin expectatuons, all very good quality.
Then it happened: Mihawk. Those moments, that fight and that ending were so glorious that it sealed the deal. And at that time there were even fools pretending Naruto was better than One piece, fools, enojoy your Boruto now.
