CL is more of an "industrial strength" Lisp. It compiles to the metal [0] so no VM is needed which makes it very fast and also appropriate for embedded applications (e.g. home automation on an RPi or Odroid). It has excellent numerical functions so it's nice for scientific computing (I use it for research others might use Matlab or Julia for), and it contains CLOS, which is probably the most powerful O-O system ever built.

If you need to write a Very Large Lisp program for an industrial application with a lot of moving parts that has to run fast, you probably want Common Lisp.

[0] Racket is now compiled to the metal now too with the recent Chez compiler integration.
