Oh, well if YOU have your kids there that means it must be the best!
It all depends on where your public school is. Private schools are definitely not across the board better than public schools, just because something costs more doesn't mean it is better.
There's a reason Moeller doesn't share their comparable data to public schools for tools like the USNews rankings, it's because parents like you would realize they are wasting money relative to many of the public schools kids could otherwise be attending. Especially a school like Mason who is 11th in the state out of over 1000 public high schools.
Lakota used to be up that high as well and has certainly slipped some in recent years, thanks in no part to an absolutely psychotic school board member who somehow earns re-election, but they are still in the top 100.
Now, if you live in some goat herder district like Edgewood or some has-been area like Norwood, yes it makes sense to send your kid to a private school to make sure they get a good education. But if you live in Mason but are sending your kid to Moeller to "get a better education", they don't make clown shoes big enough to fit that level of ignorance.
