I looked at both schools back then and liked Woodlands better. I thought the Pokfulam Sunshine in Chi Fu was a little dark, etc. in terms of premises, but liked the curriculum. However, in the end we ended up on the south side and I liked Sunshine in Tai Tam way more than Woodlands. Woodlands here is Montessori and I am not a big fan of that (I went through Montessori high school so I have personal experience). My daugther continued into ESF and I think the transition from Sunshine into ESF is better and smoother than Woodlands into ESF since Sunshine is slightly more traditional in terms of curriculum. Also ESF seems to have good experience/relationship with Sunshine and they always visit the school here prior to Y1 interviews but they don't visit Woodlands, at least not here (they usually look at the total number of applicants from a school).
It appears you have twins (me too) and you may want to look / think about which school would be able to split them (at some point) and which can't if that's what you'd prefer.
