Ligmastuck definitely ranks up there, as well as the author's other adventure, Edgestuck Chainbound.

The former has some excellent batshit antics, as well as being a celebration of all that makes homestuck interesting. A lot of deep cuts that are fun to look for.

The latter is entirely different and is one of the most compelling sburbventures I've ever read. It has a strong unique sense of direction and structure compared to other sburbventures and it really gets to the gristle of what sburb would be like for a bunch of edgy teenagers in a contemporary friend-group, while also displaying chunni badassery and sweeping land-scapes.
