By "best", it depends on whether your aim is home ownership, or investment.
For pure owner-occupancy, for instance, you wouldn't worry too much even if the flat is 40 years old; not if it's your intent to settle there for life. But lease decay is a big deal if your intent is investment; and that can actually rule out certain areas in old estates like Queenstown or Marine Parade (as the lease decay is more advanced, but prices can still be high as these are desirable mature areas).
Likewise, if the intent is investment, it may not be the "best" by the standards of a home owner. Resale flats in areas like Woodlands or Punggol, or instance, may strike some home owners as being far less exciting or convenient than one in Tanjong Pagar; but the lower price points, coupled with significant upcoming developments, can make some of them better investment prospects.
