Frankly, NONE unless you have a sponsor. Because none of them
are good and marketable unless you own your own business, or you
just want to be a simple clerk.
If you don't have a primary skill to depend on other than business
,those three are as good as the toilet paper you use in the loo.
Just more expensive.
Second or third tier universities are not recognised too well and
you will be competing against people with MBAs from first tier
universities , especially if you intend to work in Singapore. There
are so many people with MBAs ...the market is saturated .
Basically Singapore employers usually recognise NUS , NTU , Ivy
leagues ( American universities) , and Oxbridge ( UK Oxford,
Cambridge etc).
In Australia , they recognise it if you did it on their campus
grounds but usually it is best to be an MBA from Melbourne
University Graduate School of Business, University of New South
Wales, Sydney University ( because of old boys' connections) or
Australian National University if you want to climb the corporate
ladder.
