Opinion only and discussion with parents of kids there. Never set foot inside either myself but know plenty alumni.
Wouldn’t know enough to say which is better academically but parents of kids I know unhappy with pres never heard anything negative about CBC. Pres definitely has more notions. Old money.
I wouldn’t dream of sending my kids to fee paying school either. Barring one of them got a sports scholarship. If you were promising young rugby player it would be an immeasurable advantage to play for either of them if you had designs on a career in it
