i dont think this is a very good qestion. one either feels like trying something else, or doesnt. i believe a part of the difference in psychedelic experiences is also in the brain of the psychonaut, just like the effects profile on substances can vary quite a bit, and also dependant on experience, so i dont find it all that strange that someone finds some psychedelic substances to be quite similar to one another (just like for some friends i know, alea/lager/stout are all beers). i doubt anyone here will try to convince the OP to take different drugs. just stick to what you know/like for the time you consider necessary, theres plenty of info there to satisfy any curiosity if you decie later on to try others
