I'm about 99% sure someone has created this thread in the past, but I'm doing it anyways.
I think that the heel is more important, and here is why:
Just like in any story, you have to have a protagonist and an antagonist. In most cases, the protagonist is minding their own business when the antagonist gets in the way. The heel has to go out there and make people hate him. He could very easily go out there and bash on the city, but a good heel (no pun intended) develops their character so they don't have to. My favorite example, and one of the best heels, is Eddie Guerrerro in summer 2005. First it comes down to him not being able to beat Rey Mysterio, then it comes down to him blackmailing him, then to him revealing he's really Dominick's father. I HATED him that summer. Not that many heels have made me hate them. But that's what makes a good heel. They don't even need a good face (again, no pun intended). All the face has to do is come in and save the day and they get a pop. Rey Mysterio is one of the most bashed people in the IWC (for some reason, the IWC hates successful wresters...) but people loved him for beating Eddie.
However, you can't have one without the other. You can have the super baby face (Hogan, Cena), where they are on top and heel characters keep getting thrown their way. Cena's first title reign was against: JBL, Christian, Y2J, Angle, HBK, Kane, Carlito, Masters, and Edge. They didn't build much on the heels, rather they built on the face.
Now I would like to know your opinion: Heel vs. Face
