What's the fastest way to walk through an Excel Range object backwards?

Dim myrange As Range
Set myrange = Range("B3:E10")

Dim row As Integer, col As Integer
For row = myrange.Rows.Count To 1 Step -1
    For col = myrange.Columns.Count To 1 Step -1
        Debug.Print myrange(row, col).Value
    Next col
Next row

Dim vals As Variant
Dim row As Long, col As Long

vals = Range("A1:Z100") ' or whatever
For col = UBound(vals,2) To LBound(vals,2) Step -1
    For row = UBound(vals) To LBound(vals) Step -1
        DoSomethingInterestingWith vals(row, col)
    Next
Next
