No two trips are the same is especially true in the context of LSD. Literally no two trips are exactly the same. The range of effects LSD can cause is enormous and full of all kinds of awesomeness. Nothing can compare to LSD in this aspect. It is beyond a doubt the best psychedelic I have ever tried. I have only tried mushrooms a few times and they were not exceptionally bad or good. Have not tried mescaline. I have tried a lot of old school research chemical psychedelics though, and they tend to be much more scripted feeling than LSD. Some, like 2c-b, have decent ranges of effect....but they are largely much more similar between two trips than in the case of LSD. LSD continues to surprise me to this day, and I have taken it hundreds and hundreds of times. Most research chemical psychedelics I have tried were enjoyable as well, I particularly enjoyed 2c-t-2, but after having taken any of these given drugs a few times you really are not going to get anything new out of them. Taking LSD is painting a masterpiece, taking 2c-i or whatever tends to be more like watching a motion picture. Entertaining, you might watch it again a few times, and mostly enjoyable. But not creating a masterpiece with a fresh canvas and new set of paint every time. Of course this is just in general though, I have had awesome +4 experiences on research chemicals, but these experiences imo tend to be exceptional where as with LSD it just always seems to happen .
