It's a little tricky talking about "as good" or "better" than conventional wet-printing. It's different, all right, but can be amazingly good on its own terms, and without apology. (A lot depends on printing as well, just like the wet darkroom.) But it takes some effort to sort out the technical stuff. Don;t be scared off by this, though...there are challenges regardless of the path taken.
As far as scanners go, the 5000 is somewhat more preferable, but if the 50 is all you can get, I wouldn't lose much sleep over it. Either can strike a really good file with the right attention.
