Pertaining to actual shroom enjoyment, I enjoy them quite a bit, but they trip me out considerably compared to LSD.
I always, and consistently, get stuck in the circular thinking/conversations. I get pretty untrustworthy of things (I refused to watch the NBA game that was on one time because I didn't trust the advertisements on TV, and how we could only see what they wanted us to see.)
One of the most brilliant things we ever came up with on shrooms was one simple line, "Everything is of a transitory nature." We still go back to that and can find many applicable instances and few cases where it turns to be false.
For me... shrooms = philosophical, whimsical, contemplation, yearning for more, organic nature and everything that we know as life.
Acid = Fun, superficial, visual, light, enjoyable, happy-go-lucky.
And niether one is better than the other, but I definitely space shroom trips out much more so than acid.
By the way, acid =/= shrooms, really. Similar, but totally different.
