I can't see any reason for this. If the inductance
is the same, the resistance is the same, and
there are no significant nonlinear effects, as
core saturation, an inductor is an inductor, 
nothing else.
For high-frequency operation, there is the added
complication of the self-capacitance and other
parasitics, but for inductors operating at the
power line frequency this is not important.
