Bambu vs Prusa — which should I buy?

Reviewers frame this as ecosystem-and-speed (Bambu) versus open-source repairability and support (Prusa). Across the sources we read, Bambu's P1S is praised as the better value and faster setup, while Prusa's CORE One is praised for build quality and community support but criticized for cost and minor build-quality quirks. Tinkerers and those who value open hardware lean Prusa; plug-and-play buyers lean Bambu.
