this is tough!!!! meat gets enormous credit for me for the absolutely insane reveal + implementation of characters as narrators (ESPECIALLY the aliope and dirk fight via jade LMAO), but candy is so hysterically bleak, and so artfully crafted to be miserable... and that final conversation between roxy and egbert is my favourite individual chapter by far.
ahh it's like choosing between my two kids!! my two evil ass cognitohazard kids...
i THINK right now i'd pick meat. there's just so many iconic Dirk Moments™ and it does such a fantastic job at demonstrating the importance + relevance of constantly asking the question 'who is telling this story?'. like that bit where dirk starts talking in his text colour + stops pretending to be the subjects he's describing, and egbert IMMEDIATELY becomes dazed and confused, feeling like his thoughts are no longer his own and don't make sense? gah, so good.
that being said, the storyline with the cycles of abuse + familial neglect being told in the candy timeline in hs:bc is currently my favourite of the ongoing ones. super compelling for me in every way. i would kill for yiffy.
does that make my answer 'both'? what a copout lol. in short, meat for just the epilogues, and candy for hs^2 :)
