FreeCAD definitely does not have the full feature set and is still quite rough around the edges but it is improving at a remarkable pace. You still have to deal with some silly things like multiple workbenches for the same thing, lack of decent (any?) part mating support, lack of huge databases of fasteners and standards and so on, but the fundamentals are there. It's pitched as a free replacement for professionals rather than for hobbyists, but the kind of features that make hobbyist CAD software easy to use are the type of UI design that's incredibly expensive so... you get what you pay for.
