At near-identical prices, the X1C and H2S serve different roles. The X1C is Bambu's quality-focused machine: Lidar catches first-layer problems, AI stops spaghetti failures, and the established ecosystem offers years of community knowledge. The H2S is Bambu's speed and engineering machine: active chamber, 350°C nozzle, and 1000mm/s give it capabilities the X1C simply can't match.
Neither is universally better. The decision comes down entirely to your materials and workflow.
