Just my opinion but an ARF to me is the planes in my basement they are almost ready to fly but almost means i need to charge the batteries take em to the field put the wings on and fly.   RTF means the plane sitting on the runway feuled running basicly ready to fly.Point is they all come from wood, plastic, foam, fiberglass, whatever, at some point they need assembling. and aside from scratch built, most come as pieces or sub assemblies in a box. so if you will let it be
