Which Hero from Heroes of Might and Magic III is the best?

what do you think about castles, for example? is offense or armor more important for them?

I, to put it mildly, doubt that archers under Orrin will be better than snipers. Well, wizards might be better, but snipers? Unless there's no money for snipers, then the logic is clear.

sniper level 4, and archer level 2. let's compare archmages under Orrin and snipers under someone without armor specialization)))
