I know this is a point of contention with those who feel strongly about the use of 2-wire circuits, but 3 and 4-wire ciruits are a savings in wire in themselves.
I try to maximize the use of them, and shed conductors of the circuit at nearest opprotunity, or best suitable location. Like some circuits are just stanard in method now. GB/DW is a 3-wire to a box under the sink. Kitchen Counters = another 3-wire, GFI the start of each. Baths are the same.... 3-wire for vanity recept GFI, and another appropriate 20A on the other.
