Both look like they are inspired by node programming in Blender which for me was always kind of confusing.

I think what Node-RED does right is the one-or-zero inputs and no typing of inputs/outputs - most node programming environments have types for their inputs, confusing me no end. Admittedly most use colours to distinguish types, so one learns red outputs can only go into red inputs (for example).
IMHO Node programming is confusing enough (for beginners) without having colour coded inputs/outputs. I personally hope Node-RED sticks to the grey one-or-zero concept.
