Which faction do you like the most in Heroes of Might and Magic IV?

Although summoning isn't that bad, I like to use water elementals instead of sprites; they have spells for all sorts of situations. I'd like to suggest a discussion: which hero should be chosen to accompany the Druid – another Druid or a General? Two Druids can not only summon but also enhance the army and summoned creatures quite well (overall luck, snake strike, dragon strength + 2 increased summoning), which one Druid wouldn't have time for. However, the bonus from the General's tactics is lost (I personally level up an archer as a General). So, I'm thinking about it and don't know what to choose.
