This is a tricky question.
I like the [i:post_uid0]principles[/i:post_uid0] of a heel more. Do anything to win, to get one up on your opponent. They're cunning, deceptive, and use their mind as much as their physical abilities. But not everything works how it should in principle. People like Test and A-Train are heels plainly because they suck, and some people can't carry off the heel persona. Or their character isn't manipulated to how a heel character should act.
On the other hand, I enjoy faces too. Being honourable, better skilled, popular.. yeah. But they have their downsides. Their characters often have NO depth, and sometimes they're made too comical.
But it all depends on the wrestler themselves. I love heels such as Orton, Jericho, Christian, Bischoff, Cena, Victoria, Lesnar, Angle, Tajiri, and of course..the Nature Boy!! (... WOOOOO!!!) But then again, I love faces such as Eddie Guerrero (And as a heel too, if not moreso when the true 'Latino Heat'), Rey Mysterio, Stone Cold at times... in fact, I am finding it harder to name faces I like. S
I think everyone has the potential to be appealing, but it does depend on the person. But from my experience, being a heel helps. If your character is done right.. :
