The MINI+ is a small, well built Prusa that reviewers praised for print quality and easy setup. It suits beginners and print farms that only need small parts and want Prusa support. Skip it if you want more than a 180 mm cube or multi color, since the A1 mini offers both for less.

The MK4S is a proven open frame Prusa that prints very cleanly, runs quietly and can be bought as a kit for $709. It suits people who value print quality, repairability and support over the lowest price. Skip it if you want ABS without buying an enclosure or want multi color in the box.

What reviewers found
Prusa Research Original Prusa MINI+
- Tom's Hardware: Called it professional quality on a small scale and good for newcomers. A torture test model ran over 20 hours without problems; print issues traced back to damp filament. Source
- All3DP: Called it an easy recommendation with exceptional print quality and a great interface. Cons were Bowden extruder problems, no carry handle and Wi-Fi not yet available at review time. Source
Prusa Research Original Prusa MK4S
- Tom's Hardware: Called it one of the best printers they have tested. Flow rose to 24 mm3/s with Prusament PLA, and a puzzle print took 2 h 59 min versus 3 h 23 min on a Bambu P1P with smoother parts that fit. Source
- TechRadar (5/5): Scored 30 of 30 in its print quality test with a combined dimensional error of 0.097 mm, and every Benchy in its multi print test finished. Noted the high price and open frame. Source
