Hi Josh, do as done myself: learn both, Chez Scheme and Racket, you will 
not regret it.
For Chez Scheme there is the book of Dybvig online, along with other 
documentation, and for racket I suggest you "Realm of Racket".
One thing want to tell you: with chez scheme I calculate with recursion 
1,000,000! (one million factorial).
Try this with chez scheme:

(define fact
  (lambda (n)
    (cond ((= n 0) 1)
              (else (* n (fact (- n 1)))))))

Then give 1000000.

Racket will do too, but chez scheme is more fast.
A nice day for you
Francesco
