My choice would be:
(1)聖若望英文書院
(2)九龍塘宣道小學
(3)聖方濟各英文小學
(4)崇真小學
(5)九龍禮賢學校
I choose because though their standard are similar, but from the web, I think I will make the above choice.
I would choose Alliance Primary School, because of its secondary school allocation net and good result. But this school is very demanding. Besides, the kids must have interests in musical instruments.
