If you say "I want the nth", then, yes, it takes longer.  But nobody
does that with a plist or an alist -- they say "give me the value of
key", and that's an identical number of operations on a plist as on an
alist.

(Plist is car for eq, cdr + cdr for traversal, while alist is car + car
for eq, cdr for traversal.)
