Interesting Observation of ESF and RC

Hi all,

I noticed that there are many messages regarding the admission of ESF primary schools. Nevertheless the messages for RC is much fewer. Does anyone know why I believe many family do not care about the extra of about HK$20,000 school fee.

Does it mean that parents prefer ESF and not RC? If yes, why? Admission standard, academic standard or other reasons. Please share. Thank you.
