East Blue Part 1 (Start of Story till End of Syrup Village Arc) ---> 07/10
East Blue Part 2 (Baratie Arc till Chapter 100) ---> 08/10
Arabasta Part 1 (From Chapter 101 till End of Drum Island Arc) ---> 07/10
Arabasta Part 2 (Arabasta Chapters) ---> 09/10 (My Favorite Arc Drama Wise)
Skypiea (Entire Saga) ---> 09/10 (My Favorite Arc Adventure Wise)
Water 7 Part 1 (From Long Ring till Aqua Laguna) ---> 08/10 (Could be Higher, been long since i re-read it)
Water 7 Part 2 (Sea Train Chapters till Leaving Water 7) ---> 09/10 (Most Balanced Arc Overall)
Thriller Bark (Entire Saga) ---> 09/10 (I gave it 9 because it's Best in terms of Art, Comedy + Another Personal Reason)
Summit War Part 1 (From Sabaody till Escaping Impel Down) ---> 09/10
Summit War Part 2 (Rest of Pre-TS) ---> 09/10
Overall Pre-TS ---> 09/10
Fishmen Island ---> 08/10 (It has among Best Drawn Locations + It's start of Post-Ts so it felt little Fresh)
Punk Hazard ---> 08/10
Dressrosa (Entire Arc) ---> 08/10 (Could have been a 9 if not for the Pacing)
Whole Cake Island Part 1 (Reaching Zou till Start of Wedding) ---> 09/10 (Lore Dump, Some Plot Twists & Emotional Focus made it a 9)
Whole Cake Island Part 2 (Wedding till escaping WCI) ---> 08/10 (Again, it was Damaged by Pacing)
Wano Part 1 (Levely till End of Act 2) ---> 09/10 (Imo Best Chapters in terms of Building Hype & Teasing Final Arc)
Wano Part 2 (Start of Act 3 till Luffy's Fall from Roof) ---> 09/10
Wano Part 3 (Rest of Act 3) ---> Pending
Overall Post-TS so far ---> 8.5/10
So for me, One Piece is Overall 8-9/10. But due to the Lore & World Building which makes me re-read lot of Chapters, check Wikia a lot, discover References & Theories & explore it's World outside waiting for New Chapters, i give it Solid 9.
Depending on Ending, my Final Score gonna be either 8 or 9.5
PS: In general, i never give an Arc a 10/10 because there is always room for improvement, the only Arc i ever gave a 10 due to how much it really impressed me was HxH Last Manga Arc (Basically all Non-Animated Chapters)
