From an IDE point of view, I reckon it's hard to tell for a Emacs user, but the sure thing is that LispWorks the editor has more graphical widgets. The graphical stepper for example is for sure easier to use and discover than the rest. https://lispcookbook.github.io/cl-cookbook/lispworks.html LispWorks the implementation has a bunch of features.

LispWorks is a little more facile for me, I don’t think about the IDE, just think about the task on hand.

It is the same way with Clojure: IntelliJ+Cursive is just more facile for me than with Emacs.
