Common Lisp or Scheme?

I'm going to get some basics on functional programming. But there are too fucking many LISP dialects. I know all in all it's all the same shit, but between the two, which one should I use for these little studies?

(And yes, SICP is part of them)

and symbols being a data structure in CL containing a function, a value, and a property list, whereas symbols in Scheme are just interned strings.

and CL having a ubiquitous object system and Scheme having no object system. CL is CLOS.

and the completely different evaluation rules. ((foo)) is an error in CL but not in Scheme

and CL having both dynamic and lexical scope and Scheme just having lexical scope.

and code in CL at some point being represented as lists and not with Scheme (making many CLers to say that Scheme isn't really Lisp. Honestly Scheme could have syntax and the macros would be just about as easy to deal with.)

and the cultural differences, which are just enormous.

and the general emphasis in CL of using side effects and imperative techniques whereas Scheme is much more functional

and how in CL the main thing you do is make top-level definitions, whereas in Scheme you mostly scope things and have a lot of ((list in the car position) stuff to pass to the result) whereas in CL the car is always a symbol or a lambda literal.

and Scheme having built-in first class continuations.

and the general attitude of anaphoric macros vs hygienic macros
