Anecdotal evidence inbound: Went to public and private as a kid. I felt I learned more in public and gained better social skills. The private school teachers felt as if they had to make sure test scores were higher than the public schools to justify the cost and thus they did a ton of coaching and babying. It kills a kid's critical thinking skills. You also ran into teachers who didn't want to offer any sort of real consequences for some of the kids of parents who had a ton of pull at the private school. So they kinda ran wild. After going to public I was able to take up wrestling and football (smaller private schools tend to have soccer, basketball, and golf).

 

Not all private and public schools are created equal so this is just my personal experience.
