Woodland - the staff there are incredible.
Sunshine House tends to have a reasonably high staff turnover, and to the best of my knowledge, they do not offer the UK National Curriculum, but use the Ontario Curriculum with a 'learn through play' philosophy that few staff (in my experience) have ever been able to explain.
I should add that I do not have any experience of SH in Pok Fu Lam: my opinion stems from contact with their Peak, Discovery Bay and Tung Chung campuses.
My Woodland opinion stems through contact with their Pok Fu Lam, Wa Fu, Mid Levels and Happy Valley campuses.
