That's why I said the best Chinese school. PC is always a Chinese school, 30 years ago and I think will keep it as it is in the near future. PC secondary is band one for a long history.
Personally I will choose PC if my son get accepted. Even though it's a Chinese School, it's textbooks in other subjects (except Chinese and Chinese History of course) are all in English, and only the language of instruction is in Cantonese.
