Yes and no, both are a stiff with their upper-bodies, both have great jabs and base their work on it. DM is more of a brawler and more offensive though.
DM came forward but I wouldn´t call him a pressure fighter. Watch their fights, despite their different style they are similar in terms of technique and how they employ their style.
Rocky got robbed there, just like against Maske the first time. :bart Was my fav of those three back then.
