Chad Scott or Chad Nellis.. What sounds better as an Artist

Lately I’ve been wondering about my move to use my middle name as my last name in my stage moniker.   So I Need Your Opinion Please… If you never knew me, what name for a music artist sounds better Chad Scott or Chad Nellis.. Think about Saturday Night Live announcing.. with musical guest…Chad Scott or Chad Nellis… or on a CD or from the perspective that using my Middle name as my last name might be beneficial .. as in a Pen name or Stage name.    Or Does using Chad Nellis work better because its more of a branding move.   Any Feedback would be awesome.   Please add comments below.  Thanks
