The Prusa would be a lot more like your Ender. But like your Ender, they aren’t exactly plug and play. That said, they are tried and true work horses. And as another commenter mentioned, very open. Bambu, on the other hand, ships ready to print and from what I hear is reliable and simple. Unfortunately it is much more closed, and you are at the whim of a company that could just decide to kill your printer one day, or take away features with a firmware update.
