In that case you are in a good place!
HKUST traditionally had two groups of students, one more local students who got jobs in Hong Kong after graduation and the second group was international students who did not speak Cantonese and they had to go to Singapore as the result.
One of the cool things of the HKUST program is the second year exchange where everyone leaves the campus during the second year though it probably interferes with your recruiting chances...
HKUST also had a sizable part-time program I think.... But I think HKU has been catching up.
I think 10-15 years ago, HKUST was the top program. Not as certain anymore and how it will play out in the long run.
I would probably consider which program has a larger cohort and you feel as more competitive for admissions. That’s what I would probably base it on... which I think HKUST would still win by size.
