MXE was just weird to me, it boggles my mind how many people prefer it to ketamine. If it lasted half as long I probably would have experimented further. I only tried the stuff twice before basically giving the rest of my gram away to various people, it isn't so much that I didn't enjoy the drug but I found myself rarely having enough time to really explore it since it does have a pretty long duration, and I don't like to spend that many hours of the day whacked out any more. There was certainly a lot of times during the experience it was enjoyable, but equally, there was a decent amount of neutral weirdness as well. These days when I take drugs, I tend to stick to drugs that just make me feel good and don't involve a great deal of awkwardness or riding out weird vibes. If I am going to take a dissociative these days it will be either ketamine or nitrous oxide, almost definitely nitrous though.
I don't think people prefer it to ketamine so much as it's just easier to obtain clean MXE for a much lower price - or at least it used to be, it seems to have dropped off a bit lately.
I think it's also somewhat an upper v. downer thing. K is great for just completely detaching from reality and lying on the couch out of it, but MXE, because of the slight stimulant properties, seems to work better as a social drug.
If I've got K, I'm going to set up the room with some candlelight and incense, put on some chilled out music, then use it to get into a Khole and stay in that hole. It's a very meditative experience. Whereas if I have MXE I take lower doses, usually with friends, watch movies or play games, I've even gone out on it a few times and it went really well with a hard dance party.
The flip side is that, at higher doses, MXE has a slightly darker feel to it, whereas K is almost absurdly euphoric for me, and the fact that you don't eventually pass out on MXE means you can accidentally overdo it and end up absurdly dissociated while still moving around, which doesn't end well (the other weekend a friend slightly overdid it and ended up rolling around on the floor for 20 minutes - he was awake, he just refused to get off the floor and was completely incoherent, every time I dragged him onto the couch he'd just climb back down onto the floor. Was funny in retrospect, especially since he doesn't remember it at all, but a pain in the ass and a little fucked up at the time). MXE also has that speedy aftereffect that K doesn't, which can make it a pain to relax or sleep afterwards.
Fucking pyrazolam!! To my mind it's the most streamlined, effective, no-nonsense anti-anxiety pill going around. I am amazed that governments the world over don't love it because it only does one thing: kills anxiety. If you don't have anxiety, you'll say it's a bunk pill. That's how it should be dammit!
I'm a little excited due to chronic sleep deprivation so excuse the sudden turn-around: I'm not at all surprised that governments/corporations don't like pyrazolam... it's not addictive enough.. heheehe
<edit>MORE!
No, we have alprazolam!! Yeah!! Alpraz! Fuck yeah! Feels good, don't it! Spread it around so the plebs get a taste.... and.. then. ... (OMG).. make it much harder to get! YES! CONTROL THE POPULATION!
Have you tried ativan (lorazepam)? It's exactly the same as you describe, kills anxiety dead, but it doesn't get you fucked up, other than that feeling of peace where the anxiety used to be. But no loss of motor control or amnesia. Like you said about pyrazolam, I'm surprised it isn't prescribed more often, but instead it's (so I'm told) almost never given out outside of hospitals.
