ESF or SIS ?

Am from Singapore and my daughter is born in HK. She is starting nursery in Starters kindergarten this september. However, she was offered a place in ESF kindergarten in the afternoon session.

Can anyone tell me how is the ESF kindergarten in Sheung Wan?

We would like her to study prep year in Singapore international school after her nursery soon, which is more academically inclined.

But, we are also interested in ESF's curiculum and it's program offered in primary session.

Does anyone has any first-hand experiences in ESF kindergarden and starters kindergarten?

How about SIS as compared with ESF primary?

Many thanks!
