, none of the Arduino products are suitable for education. They lack the pedagogy perspective.
Please tell us more about that. What do you base this on?
There are more Arduino-based educational kits than those from any other microcomputer.
The Sparkfun and Adafruit kits and the many Chinese kits sell many to education.
I sell thousands of kits a year, based significantly on the Educational Material I supply.
What do you mean by "Pedagogy Perspective"?? Can you give an example of a different microcontroller or a microcomputer board that has the Teaching Methods provided with it that you would prefer?
