GSIS - top IS in HK How about HKIS, CIS, CDNIS, ESF?

I saw quite a few posts here in BK expressing GSIS is always on the top of the Hong Kong IS list in terms of student achievement. Do anyone have the so-called list?

The comments in this forum also direct me to think GSIS like a super star. HKIS, CIS, CDNIS, ESF have that superb status in Hong Kong too?

How do you do the positioning among the above IS at the bottom of your heart?
