Differences in Art Style Between Manga and Anime ①

There have been several works where the art style differs between the manga and anime adaptations since way back when. What are your thoughts on this? Personally, I welcome it because the anime's art style is often superior to the manga's, making it much easier to watch. However, some people do want the anime to be made with the manga's original art style, right? I'll be posting a couple of related things, but there are two such works this fall anime season with differences in art style between the anime and manga, so I'll introduce them. If you have time, please compare them.
