I don’t remember seeing anyone mention this recently (though I did see comments like this back when the pilot came out) but the reason why Craig of the Creek is a lot more on-model than SU isn’t because “the boarders are more competent than SU’s”, but because the show appears to not specifically call for the animators to closely follow the storyboard proportions (unlike shows like SU and OK KO, where that’s a specific part of the style guide), so the animators just copy the model sheets exact ly.

Like seriously, SU boarders Lamar Abrams and Jeff Liu (the exact duo that did Off-Colors, Dewey Wins, and Sadie Killer; as well as countless other eps on the show separately) did the Craig ep Monster in the Garden, and that ep looks just like every other ep.
