#2 or better is the grade supplied by lumber companies. It meets code and there is no noticable difference for deck applications. Generally #1 "only" is used when specified by a structural engineer. Which is rare, you can get maybe an extra foot or so on a span typically, so if you're out to the limit or building a beam something like that #1 may be asked for. Alter Eagle Construction & Design
