Not the only value, just that it’s the main one. Because we read comics to be entertained, not to marvel at someone’s drawing talent. If comics were only about art quality, then we wouldn’t have stick figure and paint drawings getting upvotes either.
Like I said, having something hand drawn well is always a huge positive, but it doesn’t make up for trite low denominator content.
Good content + art > good content + AI > bad content + art
Going Art > AI no matter what just means you have little perspective and live your life through knee jerk reactions.
If you go just by content, his comics suck, deal with it.
