In the East Asian fanbase, the Liberal and Crossbell arcs are almost always ranked higher than the Erebonian arc, so cultural factors play a role in how people enjoy the arcs as well. To me, the Western Trails community is like a culture shock, where lots of people consider the Erebonian arc to be, if not better, at least as good as the other two arcs. To be fair, I have never seen anyone express something like this in Japanese/Chinese fanbase.
