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)

it's nicer to just write CL like it was meant to be written.
That is what wrong with Lisps. They try to hide low level details, instead of embracing them and build directly on top of assembly language, surpasing C/C++ in being close to metal.
