If you mean isolation tank, it's not comparable because you retain control. With LSD/mushrooms/mescaline/ayahuasca there is no control on your end. It's like jumping into a stormy sea and letting it take you wherever it wants, the force is just too much for you to resist or attempt to control it. At best, you may be able to -- a (diminished) degree -- guide how the experience unfolds, but that depends on dosage and how experienced you are with psychedelic states. Finally, it's also a matter of what it does to you. LSD/mushrooms can go way beyond mere hallucinations and at high doses let you witness the fabric of perceived reality before blowing it and 'you' into pieces. There is no coming back from such annihilatory experiences, the transformation will last for the rest of your life. For some people, this is the whole point of the psychedelic experience.
