The Clojure macro system is very similar to the Common Lisp one, arguably with some improvements- The Lisp languages in the Scheme/Racket family, on the other hand, have a different (more safety-oriented) approach to macros.

Quite the opposite. Common Lisp macros are totally unrestricted, they don't auto-qualify names with the package. Also, there are user-defined reader macros in CL, unlike Clojure.
