Clear merged cells with VBA, any difference between the two formulas?

Hi,

I want to automatically clear cells across my workbook with VBA (to empty it). Certain cells are merged so the common approach of .clearcontents does't really work properly.

It seems that the following two approaches work correctly and I'm wondering if one should be used over the other:

mRange2.Value = ""

mRange2.Value2 = vbNullString

mRange2 is my named range.

Thanks
