CAIS vs VSA

We got admitted to both and now a tough choice to make
Our thoughts as below. We want a more vigorous Chinese programme yet emphasis on virtues and morality. Any ideas please, If say location not an issue

My own thoughts :
CAIS - though we are agnostic, I like Christian school which has more emphasis on virtues and morality; big n nice campus expected next summer, small class and loving teachers, so parents said; Alberta curriculum - matches with our plan to send them to Canada for college eventually- and not as difficult as IB (as some said) in especially DYP; a more humble peer group seemingly

VSA - seems better track record in IB; more truly bilingual in lower grades as two teachers at the same class; more ECAs
