People maybe like the classic look of comics rather than straight out 3d because that is what we are used to. They seem to be imbued more with the personality and style of the artist. It's the same with photographs. For years photographers tried to photograph things without light leaks, film grain, blur etc, but today while many photographs may not be taken well, the quality is vastly improved. These can sometimes look too "sterile" to our eyes, hence the number of filters and apps that add these things back onto our photos.
