In my 33 years in Hong Kong, I had five kids in Hong Kong ESF schools, from primary to high school levels. I found the standards very good although expensive but the education allowance took care of that. Not all of Hong Kong is highrise and wall to wall people. There are some very beautiful areas like the country parks and walking trails and if you are into boating, Hong Kong is hard to beat. Admittently, pollution is much worse these days. It is now five years since I retired but I still miss the place and visit regularly. I would suggest you take some time out to visit, it will help to make up your mind. Cheers, HD.
