In SG (it's probably true in other places too), MNC vendors tend to pay higher than the local companies. Among them, principal vendors, global telcos and banks are probably the best paymasters. IT professionals, who want the best rewards, should consider these companies.

Also, SG being a hub city in APAC, you will find more principal vendors and global companies setting up shop here and that translates to more opportunities to the job seekers here.

From my perspective, I tend to believe that SG offers more opportunities than MY. Just look at how much FDI is MY attracting each year VS SG's. If you are young and adventurous, I think it's worthwhile to take the plunge to relocate and explore your career here. You may not get the best offer at first but once you start building your own network here, the reward will come.
