I prefer fixed/float compared to sibor-pegged. Other items important to me are:

LTV (matters as I plan to buy condo 3 years or later)
Interest Commencement Date (determine the effective rate)
One Free Conversion (better than none)
Cancellation Fee (need to pay if not disbursed fully, even after lock in)
Legal Fee Subsidy (Clawback period)
Lock Years (think it is the min period we should stay in)
