Heavier. The article is about an hybrid vessel that uses helium to decrease its weight but is still heavier than air. I'm not a physicist, but I assume that lighter than air objects tend to have more wind resistance than heavier than air objects.

They have a larger cross-section relative to their mass than heavier than air vehicles. The larger the cross-section, the larger the force wind exerts on it.
