There are strategies for making the Contrail handle wind better, but indeed the Moment is almost certainly going to be better in wind.

I think it depends on how flexible you can be in dealing with the wind. If at higher elevations and you expect a lot of wind that you can't avoid (via lee slope of a hill, vegetation, etc) then likely the small extra weight hit for the Moment would be worth taking.

Since I already own a Contrail, I just try to avoid really exposed, windy campsites; this has rarely been an issue. A couple of times that it has I've found already-constructed rock half walls to pitch behind. Often a willingness to walk another mile or two and look for an alternate site (and not fixate on camping at a place with water or a view) will help a lot.
