QC is more straightforward pandering.
Homestuck has a lot of cancerous pandering towards the end, but the real grasp of what made the ending of Hometuck so unfathomably godawful is honestly really difficult to pinpoint. It's so obvious to someone who's read the comic, and easy to put into buzzwords, but difficult to actually capture into a few words.
It's just... the ending of Homestuck breaks you. Worse than MGSV. Worse than Weridmageddon and Samurai Jack S5E10 times ten thousand. Worse than a dozen Dragon Ball Supers.
Anything you expect for the ending of Homestuck, expect worse, and know deep in your heart that it will be worse anyhow.
