Hi lalithaa6,
Have you been to any of their info sessions?
I've seen their stats.. here's some that I had written down..
No prior experience required
100% employability within 6 months (70% of their students find jobs through the ESSEC network - ie. career services, alumni and corporate clients)
International study trip and internships (Hong Kong, New York or London.. I think)
Financial times 2018 ranking #1 in Asia, #5 in the world.
Also met this guy.. Siva, a Singaporean.. he was featured on efinancial careers . (I can't post urls here yet, perhaps you could google it yourself?)

Your GMAT score should be more than sufficient to get into ESSEC.
SMU is a good school as well.. but they're only really well known in Singapore or at most South East Asia, whereas ESSEC has more of a global brand.
If your intention is just to stay in Singapore, both schools are good.. but if you want to excel on the global stage, I'd suggest a global brand..
