I see this sentiment asserted frequently but never with comparative data or examples. I have been using Common Lisp and other lisps for over three decades and never used these two, and have no obvious way to decide if or why I ever would. The free personal editions have so many caveats in their documentation I have had no interest in trying them first hand. SBCL has suited me well enough for quite some time, especially when combined with Emacs.
