Advantage using mapc over dolist

[Heime]

Is there any advantage using mapc over dolist when looping through
a list passed as argument to a function?

(defun marsi (actm-seqr)
  (mapc (lambda (actm)
          (pcase actm
           ('armg (do-this))
           ('go (do-that))))
         actm-seqr))

(defun marsi (actm-seqr)
  (dolist (actm actm-seqr)
    (pcase actm
      ('armg (do-this))
      ('go (do-that)))))
