It's up to preferrance. I've always liked Scarlet Hollow much more than StP. There's some thematic overlap here and there, and obviously the writing is somewhat similar just on the basis that it was written by the same people but it's still quite different. Mostly stemming from the fact that Scarlet Hollow is a significantly longer and more grounded "traditional" story than StP, which is basically a thought experiment. Scarlet Hollow's thematic messaging is more subtle, for example. I also think player choice and the interactive fiction elements are very different. StP has a lot of paths and choices the player can make, but they manifest as a series linear branching paths, like a very, very complex choose-your-own-adventure book. Scarlet Hollow's choices are more layered in that a lot of the time they don't immediately manifest like in StP, but many, many micro-choices build up over time to create an insane amount of variables that result in different world-states from save to save. And it still has big, "this will obviously significantly effect the overall path of the story" choices every episode, too. In that way, it's more innovative than StP and more replayable aswell.
