Bambu made 3d printing an appliance. Before Bambu there is no way my ~65 year old mother would be able to own and be self reliantly productive with a 3d printer.
Prusa was close, but comparatively much more expensive.
I don't and won't own a Bambu, but if nothing else they opened the world's eyes to what is possible, now hopefully more friendly companies like prusa will learn from it.
