Sly is a derivative of Slime. I shy away from derivatives unless I understand exactly why the derivative is better than the original. In my view, derivatives often have poor documentation: they just copy the original docs, and I can’t tell when to do things the original way versus a special derivative way. Thus I used Debian and not Ubuntu, Vim and not Neovim, Emacs and not Spacemacs (though that’s not exactly a derivative), etc. I do use SBCL rather than CMUCL, as I do understand why SBCL is better for me: CMUCL won’t run on my platform. I look at the Sly page and I have no idea why I would want any of the stuff it does, so I stick with Slime.
