So your theory is anecdotal.
You should also check out multi-color print times on the XL vs the ASM or any other solution.
I think what Bambu has done is incredible but these are different machines for different reasons. The XL has a massive print area compared to the Bambu printers and the toolhead design I prefer. I just gifted an x1-carbon to my mom for Christmas. I'm not a hater or Prusa shill but people are just spouting opinions without data or truly understanding the differences between the machines.
