The Ender is a great printer if you're cool with it catching fire. In several of the 3d printing groups I'm in, the most common question is "what's the best printer around $300" I can get. The most common answer is something like "try not to scrimp and get the Prusa instead." That's a fairly tone deaf answer to someone truly budget constrained, though if the price is double their budget. But for an extra fifty bucks--that's a no brainer.

Print jobs can easily go 24 hours and fires are fairly catastrophic. I think Prusa just hit the ball out of the park with this pricepoint and approach assuming they are using their usual reliable, vetted components. I have never seen a report of a fire with a Prusa.

The monoprice maker select mini 2 is an excellent printer, this is basically the Prusa version of that printer with upgrades.

I own the model before this as well as Prusa Mk3. They are both wonderful. Now that Prusa Mini is out, it will probably be the printer of recommendation due to it being open source over the MP Mini.

Tbf, that really depends on the market share. In the interwebs, I've read a total of 3 - 5 reports of printers catching fire. Now, if 20% of the 3D printers are Prusas, then the rest are chinese ones, which come all with the same bad components. There is not much surprise here, at least for me.

Despite from that, the groups I know usually go like "Yeah, get a CoreXY printer instead. Moving the printbed constantly in XY direction isn't a good idea."

I agree it is hard to judge based on anecdotes, but we know Enders have had specific issues that increase fire risk. E.g. thermal runaway protection disabled by default, XT60 connectors with bad connections, defective MOSFETs.
I think, but cannot prove, that Prusa's got a fairly high percent of this broader segment of the market.
I saw someone burn their house down with a high quality Weller soldering iron. Anything with a thermal control loop of some sort is potentially dangerous and should not be left unattended. Lest you get home to a pile of ash one day.
