Harder to get a metal building to look as good as a stick frame building. Harder to get a steeper roof pitch with a metal building.
Metal is faster to build and has less maintenance over they ears, but if it starts to rust, it's a HUGE nightmare.
If you want to do anything with the walls, or have interior walls, you will build a stick frame anyway.
Easier to get big open space with a metal building.
Crew can put up a metal building in a couple of days. Stick framing will take twice as long, depending on siding and roofing.
