After rereading this, personally, in my opinion, and what I think about the art styles:
1st place - season 1 (I like how it had a very unique style with eye-catching colours, I love how the lighting made them look like they were glowing in every scene because it made the characters look lively.)
2nd place - season 3 (I like the way it looks sketchy with the unfinished looking line art but the colours need a bit more tweaking specially in the background because they just look "drawn in" instead of "lived in". It's back to the unique-ish style with some glowy lighting like season 1 but it doesn't compare to it.)
3rd place - season 2 (looks too sanitized for me, the colours also looked flat-ish when comparing it to season 1 and 3, it's the type of style that looks great in animation but it looks a bit too....still? stagnant? in webtoons. If the art style stood on It's own at the start it probably would stand out but compared to the other two it just isn't it. Idk. Like it's not bad, it's just okay.)
