I have a Bambu X1C and a Prusa MK3.9S (mostly upgraded MK3S).

The Bambu is incredible at PLA. It is so fast and consistently perfect. The 0.2mm nozzle makes unreal detail small parts. But I struggle to do other materials with it like TPU, PETG, ABS.

The Prusa takes generally whatever material I throw at it and does a great job just using the PrusaSlicer built in profiles. It's also the minimum viable printer -- it's 80% as good as the Bambu but a fraction of the complexity. I am 100% confident I could keep it running indefinitely where the Bambu is mostly proprietary parts and software.
