My exposure to stainless vs. carbon steel was mostly in the context of nuclear industry, where stainless was used only where it absolutely had to be used. But yeah, I spent some time looking at spec sheets, and it looks like modern stainless steels are actually quite reasonable for construction. But just too expensive for regular construction, especially compared to regular zinc coating.
