3-MeO-PCE feels like an unhinged MXE, manic and very serotonergic. I didn't like it in high doses. I had planned revisiting it to explore threshold dosing, but then I stumbled upon some ephenidine again, the quirkiness of which I've learned to tolerate. So plans got cancelled, but there could be something there, on the lower end. F&B called it "Dr. Strangelove" and saw potential in it for comedic writing, and I can see where he's coming from.
3-HO-PCE feels very druggy. I much enjoyed it, even managed to get musical performance out of it, but I had heart aches on the comedown. It requires its own approach, treating it as just another dissociative was very punishing.
So it's comparing apples and oranges in a sense.
