UT Rotman or Hong Kong Top 3?

I once studied MBA in a HK university, and I talked with Rotman MBA alumni. Comparing these two schools,I think If you want to stay at HK,the HK univeristy is your first choice. Although Rotman is a good MBA progame, it is not so famous as some top US business schools. so it wil not help you so much,but it also costs more.
