The verdict

Tied at 8.2/10. Buy the Neptune 4, $1,700 less.

Very close race with the Ender 3 V3 KE. The KE has WiFi, this has a slightly larger bed. Pick based on brand preference or which one is in stock. Neither is wrong.

  • The dual-nozzle system cuts print times by a factor of two. The speed increase is amazing.
