If you use steel, attach steel 'high-hat' over the steel studs (16" O.C.) It is the equivalent of wood strapping for steel. Steel studs will twist as you try to attach sheetrock to them. With the steel high-hat strapping, you will have a solid surface to attach your S/R to. It will also eliminate any flexing that can happen with steel, by locking the whole new frame structure together.
The key is to check and double check your measurements and level as you go. One stud off level can cause every one installed after it to be off, then you have to take it all down and start over again....
