I have a Prusa i3 Mk3 and a Bambu P1S and I have to disagree. They are in entirely different leagues. The Prusa was a step change improvement from an Ender 3, and the Bambu is a step change from the Prusa i3 Mk3. It definitely depends on what you're printing, but I personally saw all my print failures on the Prusa pretty much go away overnight with Bambu.
