In my experience the best developers are self-taught programmers who then went on to get a CS degree. Probably followed by people who got a STEM degree and then went on to become self-taught programmers (with a jump-start from the little programming they learned in their STEM degree). Getting good with only a CS degree or only self-learning is much tougher, though of course there are examples of both.
