I've played as a male warrior and a male wizard.
Never tried the survivor because he wears a lace collar.
What a reason, eh?
Anyhow, it's probably best to play the warrior since he's the strongest.
I like his voice...reminds me of Rolf Saxon in a way.
(Zandalor and the Dragon Rider are great.)
The wizard is the weakest of the two when you start although his magic is very effective in the dungeon until he's ganged up on.
Then you want the warrior's Special Move with a sword or knife, although I did make it through the boss fight in the dungeon with the wizard on Easy.
A few hints: stockpile all the red and blue potions you can, keep Restoration active and...need I say it?...Save Often!
