I've taken a few tryptamines with DMT compounds in them and also some other THiKAL substances. They're all the same, really. If you've tripped one you've tripped them all, it's just a matter of detail. RCs have become fairly easy to acquire if you're willing to deal with bitcoin so go ahead and try a bunch if you're interested, tryptamines are among the safest drugs considering the dose-response curve. The most difficult part is confirming what you've got is actually what you were sold, but they sell kits for that.

I liked 5-MeO-DALT the best for recreation, it was very visual, shimmery, reminded me of paisley. Easy to control, nice and brief (compared to psilocin). It wasn't very popular because it was kind of mild and the RC community is big on tripping hard, but I've heard some other similar compounds are gaining traction.

For introspection I preferred good ol' psilocybin or the 4-AcO-DMT analogue, both of which metabolize to psilocin. Easy to produce yourself in the case of the former, or easy to consume in the case of the latter.

A lot of people worry about having a "bad trips" going into a psychedelic experience, but in my opinion, "bad trips" are the best trips. They force you to spend a lot of time self-analyzing and breaking down yourself and your problems. Some of the best decisions of my life have come out of "bad trips". People who just dip their toes and avoid the stressful experience in favor of some pretty colors are missing out.
