Depends on what you mean by "better." Angel food cake is lower in fat, using only egg whites and having the volume of the cake coming from beating the egg whites. Pound cake is denser, but has more flavor and can take more flavorings being added in the baking process. With Angel food cake, it's more delicate, so you can't pump a lot of extras in it, but you can top it with anything you like. Maybe it would be fun to have angel food cake and a selection of toppings.
