Prusa used to be king.

Their QC and customer support has gradually been getting worse. Their printers are rarely competitive feature-wise. Several printer lines are quietly being retired - with bugs remaining open for years and new features only occasionally being backported from other printers. The open-source part is mostly abandoned due to cheaper third-party clones abusing it.

Don't get me wrong, I really like my Prusa printer, but in 2025 I'd have a really hard time justifying buying another one. The "Prusa premium" just doesn't seem to be worth it anymore.
