I have two sons. One of which went to a public kindergarten, hated it (crying before sleeping, etc) and we found a "école nouvelle" school (1) where he is doing fine. The other one, we ended up putting him in montessori kindergarten because of issue with the nanny, just because it was the only open spot we found.

It's like comparing "SPA and microservices" with PHP as technologies, without taking into consideration that each attracts a different type of developer. 1: state curricumum, but with specific pedagogical philosophy, focusing on confidence, team-work, etc.
