Steady versus Unsteady models!?

When precisely should I be using a steady model versus an unsteady model?
I get appropriate drag co-efficient's for a cylinder at Re~1E+4 using a steady approach, but values that don't match the experimentally accepted values when using time-averaged URANS.
Should I be using unsteady for all applications, or only when there is likely to be turbulence within the boundary layer and not the free stream / wake.
I want to go on to model aerofoils.
Any help is appreciated.
