IMO, the epilogues are arguably Homestuck At Its Best. That's probably a controversial opinion, but I truly believe it. Maybe I'm just partial to Hussie's style of prose, but it's all really beautifully written.

My first time reading the epilogues I did a weird machete order, where I'd alternate between the two every chapter. As in, Prologue-->Meat1-->Candy1-->Meat2-->Candy2, etc. My second time through I read them Prologue-->Meat|Stop when Dirk tells you to|-->Candy-->Back to Meat. They were both incredible experiences all around, but I think the second is the proper way to read them. Reading Candy is much improved by having read the first bit of Meat, and reading the second half of Meat is much improved by reading Candy.

It's not really fair to discuss them separately, given how intertwined the narratives are, but if I had to pick one over the other I'd probably go with Meat. It hurts my Serket-Simping-Soul to not pick the one with Vriska in it, but I just adore Dirk's whole style. His irreverence and nonchalance towards everything is just really great, and I adore the Narrative tug-of-war between him and AltCalliope. (It also doesn't hurt that he's hot asf, but that's a conversation for another thread) The scenes between Rose and Dirk are some of the best I've ever seen, the DaveKat scenes are great, the JohnRezi scenes are great, Meat is just great in general.

Also, if we're including HS:BC in these discussions then I think Meat clears even more. Again it hurts to say that because I love the dynamic between the Vriskas, and I really adore both timelines, but my Strider Simpage might outweigh even my Serket Simpage.
