To you GH may be 'the best next to DGJS' but that may not be the view of most people.
Most would prefer St Paul Co-ed, St Paul Convent, Sacred Heart....
GH does have her weak points - heavy homework, large class size...etc.
No doubt it is a good school but perhaps not so high on others' priority list as yours.
Why do you need to mind so much that others give up a place in GH?
So long as you are happy with her, that should be enough.
