I'd reconsider your Pokfulam option. Having moved from the midlevels to Pokfulam when number 2 came along, we feel the difference is huge and worth the extra few mintues in a cab.
That said, my commute home is 15 mins from IFC to Pokfulam - pretty much the same as it was in the midlevels. 20 mins max from home to IFC during rush hour in the morning.
Open/green views, sea breeze, wide open streets for walking with the stroller, great Park n Shop, grassy play areas, a dog park and a wise kids play room at Cyberport plus Playtown in nearby Kennedy town and of course Ocean Park.
there are some excellent low rise options around and a real sense of community in many developments.
