I honestly don't think I prefer anything. Just, don't put anchovies on it and it's excellent for me, those things suck. They even have a stupid name.
But really, anything's fine with me. I love the good old simple classic "Margherita", because its amazing due to its relative simplicity. I also like some pineapple topping, but haters gonna hate, heheh. But yeah, anything's great as long as it doesn't have nasty anchovies on it.
Man, now I'm super hungry thinking about some delicious pizza.
