There's been a bit of talk here about wood vs. steel framing. There are pros and cons for each, that's for sure.
Here's one thing to keep in mind:
one of the down sides of using steel in insulated walls with gypsum, is that it only takes 1/100 as much water retention to cause problems (mold, rot, etc) as it does with masonry; wood studs and wood paneling is in between in the amount of moisture that can be retained without problems. (Source)
