   IMO the major advantage is that you can use them for lambda lists.

Indeed, when I was hacking Lisp in the 80's and early 90's, by far the
most common application of iterating through plists that I saw was
processing &key parameters in &rest lists.  (This was the only time I
would use loop, albeit grudgingly.)  Otherwise, given a free hand, an
alist was the better data structure choice.
