I'm not sure of the value in terms of parts/capability. But since it comes as essentially a pre built or mostly built 2.4 and they donate to the voron team I can see why people would like it. That being said I've not tried one, so no clue how good it is.
Blender is European. Black Magic Design (who make DaVinci) aren't European but they're not American either (they're Australian) so a bit better
