Digital BW, The Print

I shoot 35mm film and want to print in B/W. Typically, what would give 
the better B/W print in the end, shooting in color or in B/W? I 
understand that Digital ICE does not work when scanning in B/W so it 
would take some more time correcting dust in software. While I would 
like to think it would be dust free I know that is effectively 
impossible.
