from my experience, both are intense but in different ways. my emotions are much more fragile on shrooms, but if i plan out where i'll be on them it usually turns out great. i had a week long depression after doing them once and i didnt do them again for a loooong time after that.
acid is more of an adventure imo, and a lot easier to control your trip then shrooms...however i have seen some people go a little crazy but i think that was because they were a little dose happy.
overall i keep the shrooms for when im in a good place that i know well with people i get along with,
and the acid for concerts.
