Can you provide examples for the ideal case for you? What would you like to see in Mathematica to make it easier?
As a heavy user of both, my experience is that Mathematica is more difficult initially when writing your code, but is ultimately easier than Excel because the thing you would be doing in Mathematica would be very hard to do in Excel (it is both a technical as well as maintenance nightmare).
