⚖️ Expert Verdict
The MK4S is the gold standard for open-frame quality, but the QIDI X-Max 3 wins for its industrial enclosure. If you're printing anything other than PLA, the heated chamber on the QIDI is a life-saver. However, the Prusa’s first-layer perfection and incredible resale value are hard to ignore. For a versatile shop, the QIDI is the winner because it expands your material range. But for a farm of printers that needs to be identical and reliable for years, the MK4S is the pro's choice every day of the week.
