Acid i could handle rn, but mushrooms are out. You can just kinda have fun on acid, but eventually mushrooms make you face things
Acid is streets ahead of mushrooms in terms of intensity, for me. But I know it’s different for everyone.

In the end dosage is very relevant and of course even more important: set and setting

I do think acid is more homogeneous and easier to dose appropriately though (YMMV) But the length of a trip can make it challenging.

Do heroic doses of either, shrooms for me result in more body load and are more introspective chaotic/mystic. Acid more energetic/clearer/“Neon” wider headspace. But in the end setting is what I think is most important for how the trip plays out (I had my best and worst trip on shrooms).
