I've been window shopping the Apron stores to get prices on drywall for my basement. I see that they have a few different options Ultra-light, High-strength Lite, and TE (Toughrock). I've seen reviews that say the ultralight stuff is crappy: peels too easily compresses too easily, sags. But the price goes up significantly on the other products. So I'm looking for more info / opinions from you guys. For instance, does the lighter stuff require more fasteners for a ceiling? Right now, i'm just doing the ceiling, so the lighter stuff may be preferable and I'm not worrying about water resistant boards up there.
