This may be late but do you have any thoughts on Trinity Metatronius because I'm curious about it's ranking.
Trinity Metatronius is a really rewarding chapter on pretty much every front. Mash's arc goes hard, and so does Lilith's entire characterization. The moral questions of Cosmos in the Lostbelt, as well as Kadoc's and Anastasia's participation in the prologue, are finally put to the forefront after 7 years of lying in the background. Kotomine is given a perfectly meaningful and original character climax, because his part in Final Chapter sure wasn't it. Just an overall appropriate wrap up to story Cosmos in the Lostbelt grew to be with the years, contrary to Final Chapter being more of a wrap up to the story Cosmos in the Lostbelt was originally planned to be.
Granato felt genuinely cozy as a setting, making for a main party I enjoyed a lot more than the sum of its parts. And the Ace Attorney segment at the climax manages to be even more engaging than the Maison Ikkoku sections. Traum always felt emblematic of Higashide's FGO career the way an Ordeal Call is supposed to be, but Higashide still managed to surprise in a way that fits the bill. He spent all of Part 2 writing White Day events that strip FGO of its action and forces its cast to engage puzzles in the framing of a different genre, so OC4's courtroom drama definitely works as this culmination of Higashide's Fate/Grand Order.
It's weakness is obviously its horrendously side quest hell (literal), but I was overall pretty willing to let the plot take its time because I felt it directly asking for my own patience through moments like Amakusa being depowered but he was unable to wait for Chaldea's arrival, Moriarty's direct warning that it would take a long time to assemble our case, Sloth brainwashing the main trio to save them from their own impatience, and Judge's overall rashness being what puts her at odds with everyone else. Of course, this only works because the payoff is well worth the wait.
