There's really not much difference between Ruby and Python. I prefer Python and would argue it's a little more versatile (at least in terms of library support - people do command line scripts and scientific computing in python whereas Ruby is quite webdev-focussed) but honestly, who cares. Pick one or the other, learn it, have fun with it, use it to solve problems. And then make your next language something radically different from either of them (Haskell?)
