There's got to be pretty much zero benefit in solving the same programming problem in the same way. However I have found considerable benefit in solving the same programming problem in different ways. So using different languages, programming different styles (I once wrote a program strictly following the Law of Demeter just to see), implemented a games rules system as a bunch of Command objects and then doing it again as a stack base DSL. This kind of "kata" (I join you in hating on the co-option of the word) has helped me expand my programming skill set.
