I recently agonized over this decision a bit and went with a Bambu. When it comes down to it, the prusa printers are just really hard to justify given that you are paying more money for fewer features even if you assemble it yourself.
I agree with what others have said that the reliability and longevity of Bambu printers is a concern, but frankly if I’m still into printing in a number of years and Bambu starts to really enshitify, I’ll build a Voron or get something even better that hasn’t come out yet.
Because ram is incredibly cheap and developer hours are incredibly expensive. I think it’s a bit silly too but there’s just no financial incentive for companies to care about memory usage when they know most consumer devices have tons of extra headroom.
