For me, there is no mind-fuck with 2C-E. It's crystal clear and analytical. I seem to analyze things and come to understand them in new interesting ways, but nothing like the mind-fuck from something like mushrooms or high-dose LSD. I've taken fairly high doses, unmatched clarity.
2C-B also has no real mental push. It certainly gives you a positive mood, and I recall always getting this "70's pimp" vibe while on it. Also taken really high doses with this one, it's been awhile so I don't recall, but it's interesting for sure.
From my experience with the two, it sounds like he's describing them right. In my experience at least. 2C-E has much stronger visuals, and no mind fuck, just an unmatched clarity. OTOH, 2C-B has less intense, albeit beautiful visuals and a great body high, more of a 'novelty' psychedelic. By that I just mean, don't expect a full blown psychedelic experience from that one. But 2C-E is a real contender for that.
