So, in finishing my bathroom remodel I'm now just wondering, conceptually, why/how green board sheetrock works any differently than normal sheetrock if it's textured, primed and painted in the end anyway? It seems to me that the common denominator for both (in a moisture area) would be what's closest to the moisture, which would be the texture, primer and paint (all of which is covering the wallboard anyway), no?

Greenboard in theory has more water resistive properties than regular sheetrock. If it gives you a warm and fuzzy feeling, use it in the bathroom. In a moisture laden area, where there will be tile, greenboard is definitely not used. Rather, concrete backer underlayment is used and the tile applied over it.

IMO greenboard has limitted uses. It doesn't paint as well as regular drywall and as noted, once the drywall is primed and painted with enamel - it has enough moisture resistance for most applications.
