I agree with a lot of what’s being said here in terms of not splitting hairs because of League Tables. Pretty much all of schools discussed on this thread will get your child to the same outcome!
I have an older DC in a super selective (younger one going through the 11+), and what’s key in the teen years is self-esteem and mental well-being, a lot of which is determined by friendship groups. Friends play a much larger role as they get older and parents less so.
The other key IMO is self-motivation. Parents can’t monitor their kids as closely when they are older, so if you have a self-motivated kid, they will do just as well at PHS or G&L or SPGS or whatever.
Furthermore, I’ve seen first hand what happens when parents ignore the prep school’s advice and push their kid really hard into a super selective. They might be ok once there (a gamble) but I’ve seen what happens when they aren’t. The parents have the ‘badge’ of saying ‘my kid goes here’, but what’s the ultimate point? The kid’s self-esteem really suffers and it becomes a downward spiral.
