General advice: don't let the desire to learn the "right" thing prevent you from learning, period. Eventually, it's better to just make a choice and dive in, then to spend more time trying to figure out which one is "better".
Absolutely learn both! Make sure you learn macros well (I suggest Let Over Lambda) and Haskell's powerful type system. I know Clojure and macros pretty well, but learning Haskell the last couple months has been incredible. And then learn Forth, J, Prolog, do SICP in Scheme, etc. ;)
