Decent value for money mostly:
It has a rather sturdy "unibody" frame and can be assembled within minutes. Separate stepper motor and endstop for each Z-axis. The ultrabase is awesome to print on, I never had to use glue or tamper with bed adhesion otherwise. Firmware is open-source and can be replaced. Comes with a spool of filament.
The Ender 3 certainly rivals it in value for money, but if you can afford to pay a little extra, the Mega S seems to be the better package.
