What do you value? Dominance, or is it the workhorse? Where does the line lie between performance and reliability?
Ultimately, I feel drawn to the workhorse. Give me a guy that gives you the innings. That's not to say that a guy who posts more dominant numbers in fewer innings is a lot worse, but games are self-contained events, and there's a certain number of them. Maybe you have a full run better ERA than another guy, but if he pitched almost twice as much as you did, he probably had a positive effect on more actual wins than you did.
