I don't even care much about cost, but the Bambu Lab printers are simply better. I have been selling my Prusas (MK3S+ and XL), because they are just too much of a hassle. Prusa has fallen behind in R&D, the Bambu Lab printers work better, are more automated, have more nicely engineered features (having to babysit my XL and wipe the dripping filament off the print heads was such a disappointment).

And yes, I have had to fix both brands. The repairability of the Prusa is largely a myth, you still need to order replacement parts from Prusa, just as with other brands.

I wish Prusa would catch up with their R&D.
