Your list is super unorthodox, Part 5 being dead last, and Part 1 being up that high.
Part 2 being high is actually believable I have a few irl friends who rate it at 1 for the same reason you listed.
My list aligns with Fuji's the most, maybe PMY too at the top end. I just rate Part 3 very highly because the last stretch of Part 3 is the greatest stretch of Jojo, it is literally 12/10 peak after peak after peak concluding with the most iconic battle with the most buildup between Jotaro and Dio.
Btw Is part 8 finished?
