Scheme or Common Lisp?

Yes, it's a “which programming language to leran ???” thread, but this time it's ...more specific I guess?

So I already know C ^{_{and Perl}} and wish to acquaint myself with other paradigms than the procedural and object-oriented ones I've become uncomfortably familiar with (i.e., functional). I also intend to learn Haskell at some point in the future in order to complete the holy trinity of syntaxes.

So, /anus/. Regarding the thread title, what are the differences that you find make you prefer one Lisp dialect to another? Is there even much of a difference? Or did you just choose one as your way of saying, “I've read SICP”?

In what way? It's already proved that hygienic macros are doable in CL portably. The cool things about hygienic macros is the whole way they capture the lexical environment the macro is written in, but that can also be achieved in CL through a variety of techniques, however I can't remember a single case where I needed to do that intentionally, and I've written a lot of macros.
