In terms of basic city setup (border pop + monument + tile improvements), Expansive saves more hammers: 30 (granary) + a few per worker vs. 30 for monument. But Creative still wins (IMO) since you get the full BFC almost straight away, and it lets you wrangle tiles away from other civs with minimal effort.
That said, for an easy start I prefer Inca over either of these traits.
