Which is better for interior walls, metal studs or wood studs?
"Non-Engineer" answer: Either one will work
Explanation: While both materials are used to achieve the same goal, there are some differences in how to build with them as well as their performance. Wood studs remain sturdy on their own while light-gage metal studs tend to be flimsy until the sheathing (drywall) is attached. When cutting wood studs, a mess is created from the saw dust, while the light-gage metal studs are cut with aviation snips leaving no mess. Another difference is that wood studs are typically constructed faster using nails whereas the light-gage metal studs require screws and take a little longer to construct.
With respect to performance there are two major differences. The first major difference stems from the fact that metal is capable of withstanding much higher temperatures than wood. Therefore, if a structure is exposed to fire, the metal studs will typically perform better than the wood studs. The second major difference has to do with the materials ability to absorb moisture. Namely, wood is capable of absorbing moisture such as ambient humidity where as metal is not. Therefore, during summer months or even just long hot showers can result in significant elevated humidity levels that, if not absorbed, can lead to problems.
Commentary: After understanding the differences, the big question is; is there a difference in cost? That depends on where the structure is being constructed and who the contractor is that will be doing the work. Different contractors may be more comfortable building with wood studs or light-gage metal studs, which can increase or decrease the cost of labor. The material cost of light-gage metal studs is slightly higher than that of wood, however, the light-gage metal studs are easier and less expensive to transport and store.

Always seems to be a debate - wood or metal... I think you bring up some great points. The metal framing is the most important component of any home. For that reason it is crucial to begin by doing your research and the best place to go for this is McGraw Hill's Sweets Directory of Construction Products. While I do work for them, they have honestly proven to be beyond helpful in all of my home improvement projects. They are really worth checking out.
