One thing I've noticed is that people who already live in steel-framed houses often mention how solid the structure feels. My neighbors finished building theirs about three years ago, and they still say they haven't had to deal with problems like twisting or shrinking that friends experienced with wooden frames. Watching their project made me realize that planning and quality installation probably matter just as much as the material itself. They also liked that steel components arrived with very accurate dimensions, which made the whole building process smoother. I don't think steel is the only good option, but for durability and consistency it certainly seems to have plenty of advantages. Every project is different, though, so it's always worth discussing the design with experienced builders before making a final decision.
