Yes, I've had an MPC1000. I didn't get into it that much because I prefer the SP1200 which I still have.
I'm not into playing synth top trumps so 'completely outclasses' doesn't mean much to me. Not even sure they're comparable machines to be honest.
The Machinedrum was partly Elektrons take on the SP1200. They've always leant in that direction. The MPC seems to appeal to finger drummers and hip hop fans more than Techno producers. Probably the pad layout and feel has a lot to do with that. That's one thing about Elektron that's always divided people.
I'd guess you wouldn't like Elektron gear, maybe stick with the MPC.
Also to answer your question regarding Techno. They're popular because they were developed as a tool to make Techno so they're good at it.
