They have a bit more polished UI than Emacs has, which even in the GUI version is mostly a thin shell around a fundamentally character-based UI. Personally, I have stuck mostly to Slime and Emacs, as it works well and I prefer the native Emacs feel. Another advantage of the Emacs route is, that it works with most Lisp implementations, so I was able to use Slime with SBCL and Allegro, sometimes in the same Emacs session :)
