No way! ok. I have to qualify that.
General population: Singapore probably has more English speaking
folks (not necessarily perfect english type)
The schooled: Singapore still has the edge because most HKers do
not practice it in their daily lifes. They can probably read and
write as well, but spoken? Nah!
The higher education: Singapore has a slight edge because (in my
opinion) our spoken style is more international, whereas the HKers
has a very sing-song style. The tone usually start slight high
pitch and drops slightly lower at the last word or syllabus.
Cantonese? They win hands down.
