Sure their opinion matters as much as anyone else's. But the question is, from which POV they got this opinion, or better said: Did they breakthrough on it? Did you ask your friends about that?

I wouldn't call it like that, personally. As has been said, and as one can read from several reports, it seems DMT can also get you there. But as it seems usually for this you need quite big dosages of DMT and you still only get there inconsistently.

So I wouldn't say it "surpasses the DMT experience". But rather, that it goes beyond the "normal" DMT-Breakthrough.

Or explained in another manner:

5-MeO-DMT seems to deliver complete ego-death. Any sense of self is gone.

On a "normal" DMT-Breakthrough you only get a partial death. You lose complete connection to the body and therefore also to this body bound reality. But you still experience a self, and experience e.g. entities apart from yourself.
