How they stack up

Bambu Lab A1

The Bambu Lab A1 is easier to set up and faster out of the box than the Creality Ender 3 V3 SE and Ender 3 V3 KE, and its AMS lite multicolor is more polished than the Anycubic Kobra X's built-in system, though it costs more than the Elegoo Neptune 4 Pro and is less open than the Klipper-based machines.

Elegoo Neptune 4 Pro

The Elegoo Neptune 4 Pro matches the 500mm/s speed of the Bambu Lab A1 and Creality Ender 3 V3 KE with open Klipper firmware, and it is faster than the Creality Ender 3 V3 SE, but its calibration is fiddlier and it lacks the multicolor of the Anycubic Kobra X.
