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

I would vote for Serena from the Tower, but she's not available. But in a pinch, I'd go for Oris from the Castle, but she's not available either :(

Is this a joke??? Or does Serena really have some secret?:confused: I recently read that Astral is a pretty good mage, and I read it from a good player. Seriously. As for Oris, besides the almost guaranteed chance to learn Blind, which the AI uses on behemoths, by level 10-15, I haven't noticed any other significant advantages.
