Counter opinion: anime is better in terms of animation but a lot of anime still looks a lot alike, similar to how a lot of cartoons nowadays all look like Calarts style animation.
What I mean by that is, I think for awhile anime pretty much all looked the same, the same way Western cartoons do now, only difference is anime was always superior in animation.
Also, anime is a gigantic fucking genre and Japan has literally thousands of anime shows appealing to different demographics including adults, whereas most Western animation is aimed towards kids.
In other words, comparing Western cartoons to anime is apples and oranges and a retarded comparison.
Also here's another unpopular opinion: art is subjective.
