I don't know if this will be helpful, but we are using the old fashioned black paper wrap.....don't know what it's actually called, but our builder prefers it for it's proven durability. (He is relatively young, definitely up on the latest trends and practices, yet still prefers the black paper.) Tear down a 50- year- old house and that black paper is still in there working well, not worn out. I have no idea if it is any more or less price-wise, but I believe it is greener than the Tyvek-type wraps as they are plastics, so maybe you'll want to check into it?

It is probably "Raindrop" housewrap by Greenguard. It has tiny vertical drainage channels which allow drainage behind the siding similar to DuPont's DrainWrap (StuccoWrap is the same product) which has wrinkles. Tyvek is probably a more water resistant material because it is non-woven but whether you need a drainage wrap depends mostly on the kind of siding and the amount of rain. For instance, it would serve no purpose behind vinyl siding or in Arizona.

Design the wall as a total system and avoid getting caught up in individual material marketing rhetoric.
