The verdict

Buy the Neptune 4 Pro. 8/10, #28 of 51 FDM printers.

The Neptune 4 Pro is the move if you want linear rails without paying Bambu prices. The Creality V3 KE is the comparison to make: same price, different ecosystems. Creality wins on community, Elegoo wins on hardware spec for the money.
