it depends actually.
Some people still think SIBOR is good especially at the current month whereby SIBOR is at 0.8% region, but we all know this won't last for long.
currently there's attractive board rate going at 1.38,1.58,1.78 for 3 years lock-in, but at the end of day, still recommend to go for fixed rate at 1.78,1.98 2 years even if it means that you're paying higher because once board rate goes up, your lock-in for 3 years ties you down and you can't do anything besides paying reluctantly.
