I feel pretty good about it. The main two battles, Cynthia and Leon were absolutely spectacular and well written, with pretty good animation too and in Leon's case, God tier animation
Aside from that, we got pretty good battles with Ash vs Steven and Iris vs Cynthia even if they did have some flaws, and Lance vs Diantha was written pretty well too even if it was more static. While they definitely werent as High quality as you'd think from champions battle, they definitely were still entertaining and much better than most league premilinaries battles in the past
So in terms of your normal leagues, The PWC was definitely on par if not better thanks to its main two battles elevating it
Not to mention we know the anime production was basically in shambles, for them to give what we did get despite all that is a major victory in my books
Ash vs Leon - 10/10
Ash vs Cynthia - 9.5/10
Ash vs Steven and Iris vs Cynthia - 8.5/10
Lance vs Diantha - 7.5/10 altho a 9/10 in terms of writing
Leon vs Diantha - 4.5/10 (but then again it was pretty much skipped, and the Charizard vs Diantha fight in vaccum was pretty nice)
Leon vs Alain - 6/10
Sure Leon's battles prior to Ash were controversial, but i think all things considered, they have aged well.
PWC certainly had tons of flaws, and the narrative buildup to it should have been better and the breaks/recaps in between did hurt the pacing, but overall, I think PWC was an excellent arc and one of the best "league" arcs, with Sinnoh league ahead of it but confidently i can say beating Kalos, Alola and Johto leagues
