Not true. The additional resistance in the secondary circuit alters the voltage wave form and reduces energy at the spark plug. This can increase misfires, which can be felt as a slight idle roughness, and resistor plugs can also increase HC emissions enough to bust a field emissions test due increased misfires.

Many long time owners have tried resistor plugs - that's what most catalogs now show - at one time or another and gone back to non-resistor, which can be tough to find.

If any ignition coils got "fried" it was probably some other cause than resistor plugs.
