I tried to use 3-MeO-PCP as a replacement for MXE over the past few days, due to concerns about bladder toxicity. I should have followed my own advice, earlier in this thread. Doesn't work.
3-MeO-PCP is not a recreational drug, unlike MXE, IMO. Has a pretty cold and sterile feel, lacking any of MXE's warmth. Also, the chaos and confusion of 3-MeO-PCP makes it rather difficult to enjoy an activity like playing online shooters, whereas on MXE I found that the lucid serenity of the high would at times enhance my virtual sharpshooting skills. Thirdly, MXE would leave me feeling rather optimistic and clearheaded in the following days, but after a two-day bender on this stuff, I feel agitated and confused.
That is certainly not to say that 3-MeO-PCP is a worthless chemical, though. I would say with certainty that for a serious psychonaut, interested in accessing the more bizarre states of consciousness possible, and plumbing the mind to the most arcane depths, 3-MeO-PCP is much more useful than MXE.
I had some pretty interesting and unique experiences during my recent experimentation. In particular, I remember a fascinating experience wherein some deeply repressed emotions came billowing up to the surface of my consciousness. I became so completely and utterly detached from my own emotions, I think that I no longer felt the need to bottle them up, and so out they spilled, and I began sobbing uncontrollably at a pain I practically didn't know I had. But, in an odd sense, because of the intense dissociation, I wasn't really sad -- it was this completely mechanical, emotionless sobbing, as if I were a robot executing a "cry" function. Very interesting stuff, but again, far from recreational.
