Not my discussion but I am going to chime in here.
I don't like most AI because it's try to make a cartoon into something it's not. Real people or animals.
Some artists thing that because they can add all the bells and whistles, shadings of skim tones and items, and make it no longer a cartoon and not close to a real thing.
Rule34.paheal at least separates them by their borders even though they don't usually have to. Some artists just use them to tweak the creation but it all falls into the style of the art.
