Interesting comparison, thanks; the window based tools don't seem to have much advantage compared to e.g. SLIME, isn't it? Allegro doesn't even have syntax coloring.

And yes, I have real project experience – a lot of Commmon Lisp libraries at https://github.com/40ants and also I'm developing a hosting for CL library distributions: https://ultralisp.org
One advantage for a lot of people is that other IDEs don't use GNU Emacs. That's an often requested feature. Another advantage is that one gets more developments tools, incl. various browsers, a GUI toolkit, an interface builder, more native look&feel on platforms like Windows/Linux+Gtk/macOS, ...
Allegro CL has syntax coloring, but not in the web version as it is now.
