Bambu Lab P1S vs Original Prusa CORE One

The P1S has 13% more build volume (16.8 L against 14.8 L).
Per litre, the P1S is the cheaper space at $24 against $81.
Only the CORE One publishes a flow rate (24 mm³/s, roughly 300 mm/s of line speed), so the other's speed claim cannot be checked.
Only the CORE One drives its chamber (to 55 °C), which is the difference that matters for large ABS and ASA parts.

Bambu Lab

P1S

~$399 · 16.8 L

A first enclosed printer, or a second machine to run abrasive and higher-temperature filament.

Prusa

~$1,199 · 14.8 L

ABS and ASA work where you want an open, repairable machine rather than a sealed appliance.
