Every school is probably different. When I looked into a Waldorf for ds4 it initially sounded nice but I specifically got freaked out by the way the kids were forced to do art: they were only allowed to shade, no drawing lines, and the use of colors was very limited. Free outdoor play did not equate to self determination in other areas and I wasn't comfortable with ds being made to follow rules that I could find no sense in.
On the other hand, there's always a school that overall has the least bad things. I know for example my mom sent my brother to a religious preschool despite them not being religious, they cringed when he came home singing religious songs but as parents and home life have a strong influence, the impression on him was fleeting.
