VBA over-write identical worksheet-ranged-cells only if receiving sheet's cell is empty

Facts:

Sheet1 has range Named "FirstDataSet" of cells A1-Z100
Cells in "FirstDataSet" contain data in about 20% of the cells

Sheet2 has range Named "SecondDataSet" of cells A1-Z100
Cells in "SecondDataSet" contain data in about 20% of the cells -
... but not the same data in similar ranged-cells.

I realize that I could:

For each myCell in FirstDataSet
If myCell.value < ""
myCell.value = SecondDataSet.Range(same range as myCell).value
End if
Next myCell

Is there a smarter/efficient way to use broader range base than Each myCell?

My guess is no - because the evaluation is on a cell by cell basis??

But I am open to learn!
