Missed this when it came up, but FWIW, plenty more differences have
crept in since then as I realized that cl-indent.el in Emacs was
sitting still and I stopped worried about staying in synch.

Partial list:

* Test suite!

* Support for named indentation styles.

* Better DEFGENERIC and DEFMETHOD indentation.

* Better lambda-list indentation.

* LOOP indentation, as mentioned.

* Aligning keywords in calls.

* Better handling of comments. There is still plenty of work to be
done here, though. Comment indentation remains my biggest irritant,
but at least we now get

        (foo ;; Deal with bar
             (bar)
             ;; Deal with quux
             (quux))

instead of

        (foo ;; Deal with bar
         (bar)
         ;; Deal with quux
         (quux))

* CL feature expression handling. It's not perfect, but a damn sight
better than nothing.

* Better DEFCLASS and DEFINE-CONDITION superclass list indentation.

* Fixed handling of incomplete destructuring indentation specs.

* Don't consider DEFAULT, DEFINER and DEFINITION to be defun-like.

* Indent boa-constructor lambda-lists properly.

* Fix handling of , and ,@ at the start of the indentation.

* Indirect indentation specs. (late bound)

* Fallback method for trailing expressions on prev line: Emacs'
calculate-lisp-indent doesn't indent

        (foo (or x
                 y) t
             z)

right, but would align Z with Y.

* Support for IF*.
