Effects - Mescaline vs lsd and shrooms trip

[actarus]

Swim's always been interested in peyote and mescaline, he heard it's a "gentler" trip compared to lsd (not sure about shrooms), and due to its well-being/euforic effects is less likely to have a bad trip especially for newbies, and could this be also because mescaline is a little chemically related to mdma?
And for gentler swim did not mean at all less mind-blowing and inner-searching, maybe just less "mind-fuck".

For those who have tried 'em all how would swiy compare em?

ps sorry for the cross-posting, swim posted this here since it's mescaline he is really interested about.
