In Heroes of Might and Magic I and Heroes II, each faction had only one hero class, and they only differed in starting stats, portraits, appearance and biographies. Heroes III introduced two classes per faction, with different probabilities of learning different skills.
Heroes IV also had two basic classes per faction, except the Stronghold, which only had the Barbarian, but heroes who advanced their mastery in various skills could get advanced classes (for example a hero with three different magic skills would become an archmage) and receive extra bonuses. Heroes in this game don't have any unique bonuses.
Heroes in Heroes V have similar abilities to those in the third game: each hero had his own specialty, though different heroes of the same class had identical specialties.
