It’s among several good options right now, we’ve entered a new era for fast, high quality home 3d printing. I got the MK4 because I’m already in the Prusa ecosystem, I expect (from experience) that this machine should just work for many years, and I know that if it doesn’t Prusa’s support is the much better than most companies at the price point. Additionally, I have some specific applications in mind that I think their “Nextruder” and load sensor will excel at.

That said, Prusa is trying to hurriedly catch up to recent competition and they have shipped a somewhat incomplete printer (at least in terms of firmware). If you want a full look at current state of the MK4 this Tom Sanladerer video is going to be better at it than I am.
