thisOda simply cause he is doing it consistently nonstop.
Togashi is up there but he hasn't shown he can keep his work top tier on the level Oda has for that long. If Togashi was constantly pumping chapters out and his quality didn't drop (Like Oda) then this would be a tougher decision.
Edit:
-Creativity = Oda (pretty easily, he managed to make a guy who walks around in a pink fur coat badass)
-World Building = Oda (close but Oda does it best)
-Characterdevelopment = Togashi (Oda's main cast is fairly stagnant in comparison to Togashi's)
-Themes and symbolism = Oda (Too many to count, too many references)
-Complexity = Togashi (Most complex characters in Shonen, example - Meruem, Sensui etc.)
-Suspense and mystery = Togashi (Mystery department is close probably Oda, but HxH definitely has more suspense due to people actually dying)
-Plot and purpose of stories = Oda
-Coherency and cohesion = Oda (Everything is planned out from start to finish, planning is on another level from Oda)
-Logicality (no asspulls, dues ex machines, plot holes etc.) = Togashi (too much deus ex in One Piece)
- Consistency = Oda (Togashi hasn't been doing it for as long as Oda, he keeps stopping)
based off your metrics I have
6-4 in favour of Oda.
Togashi will win u ban Dragon Quest in Japan
