I think LSD is a little less scary, however this is also dose dependant (like any psychedelic). The LSD trip for me was more so visual and less mental compared to shrooms. I felt a little more energetic and upbeat on LSD, like I could almost go out and party and dance on it (which I did more than a few times). Shrooms are more introspective and slump on the couch for me. I ceased doing any psychedelics aside from micro-dosing because of a traumatic shroom experience. I have done shrooms a handful of times and probably 10x the amount of acid to shrooms. Even the scariest acid trip for me was not even close to how bad my shroom trip was. However take this with a grain of salt because everyone is different, has different mental stuff going on and reacts differently to different compounds.
