As with everything else in life, there are good private schools and there are bad ones and there are good public schools and bad ones. You'll have to compare those schools that are available to you.
The one thing that does bother me when I speak to SOME parents who send their kids to private schools is that they seem to think all the problems that kids face today seem to stop at the private school door and they don't have to deal with them. I actually had a parent say to me "I'm so glad my child goes to private school so we don't have to worry about drugs and teen pregnancy!" I was shocked. She didn't think these things could possibly touch her children because of the school she sent them to. If a private school is the best educational setting for your child, great but don't assume that you don't have to still deal with educating your children about these issues because they do still exist and private schools actually tend to do a lot less talking about these issues then public schools so the burden is even more so on the parents to educate the kids about these things.
Good luck,
