Disagree. The better comparison is Core One vs X1E. As frankly the main selling point of the X1E is Active Chamber Heating.
With your logic you can also say you can just get 2 P1S printers instead of an X1C, but an X1C is still sells just fine.
The Core One doesn’t have chamber heating, it just has chamber exhaust. Not the same thing.
