I don't love the heroes for their bonuses, but for their faces and backstories ;)
Among the Knights, my favorite is Sir Mullich.
Among the Clerics, it's Adelaide.
Among the Rangers, it's Enova.
Among the Wizards, it's Astral.
Among the Beastmasters, it's Bron.
Among the Battle Mages, it's Oris.
Among the Elementals, it's Ciel.
I think I've listed all my favorites (something made me repeat "among" :D).
