The state schools you have listed are great, so I guess this is about your own feelings on a type of education, rather than whether the state schools stack up. To be concise, tho' a tad blunt; if you lack confidence in the state system, go private. If you feel that private education is not worth the money because your children will get a perfectly good education in the state system and will benefit from the greater disposable income your family will enjoy, then I would go with the Belham as your closest school, with the others ranked in whichever order you like.
