You can probably maintain your Prusa forever. The Bambu... not so much. It is a philosophy choice here and the 3D printer space is vastly more complex and nuanced for many users than an appliance that has one simple job. Yes if you /just/ want to print stuff and treat it like an appliance as a curious consumer dabbling in the space the Bambu is great. That was never Prusa's target. I don't think the comparison is very strong.
