I'm late to this conversation, but the subject matter is important enough that I feel the need to weigh in. The thing is, there are pros and cons to both. Pies have fruit, which can be very tasty, but cakes typically have frosting, which is sugar heaven. Then there's cheesecake, which I think someone mentioned already is technically pie.
Really, when it comes to dessert, I prefer anything smothered in caramel, which is more likely with a pie than a cake. Caramel Apple Pie is divine. I nearly went for "Other" because I could eat a bowl full of caramel covered ice cream any day. Which would be a pro for cake since cake is most commonly served with ice cream.
In the end, I voted for pie because Cheesecake and Caramel Apple. I couldn't vote for "other" because the poll is which is better. Even if you don't like either one, you have to have a preference of one over the other. So pie it is.
