XPS or EPS?

My builder is going to use 5 inches of EPS rather than 4 inches of XPS on the exterior walls. His reasoning is the same insulation value for a little less money ....any pro's or con's either way?
Thanks,
Bob

Bob,
Pro: EPS is more environmentally friendly than XPS.
Con: You need longer screws.
