igor and the other guy are both psycho murderers... both are evil, both worship evil... neither will kill you because you are a dragon and they are bound to a magical sentient island that teleported them to itself and will strike them dead at its whim should they not serve you. (or should you chose the other person to serve).
To be fair, if you metagame, none will kill you so it comes down to rewards.
Trainer: Hermossa = more skill points as rewards than slayer
Necromancer: Igor = Magic armor for creature, other guy = physical armor for creature. (Both give 2 skill points for quests)
Alchemist: Barbosa gives more skill points as rewards. Allen brew has some bugs that can make it impossible to complete (and I still don't know what it does); and allen requires you let him have poition of wisdom instead of drinking it yourself.
Enchanter: Guy with wife gives more skill points as reward.
