Why does everybody compare these two apps. They target two different audiences, and the goal is to accomplish two different things. There is no drawing a comparison between these two. Try SciFly and Wings or BiiPlane and BiiBall. Or anything except between the two. This has come up countless times, and you can't provide a real answer. I own both, and play both. I think the controls on BiiPlane are better, and SciFly is a great dogfighting game, a genre that is almost completely missing on the iPhone. But they are for different people. Stop drawing comparisons. And goodness if people don't start asking which to buy when both are $.99. Its less than a pack of gum. Or a bottle of Coke. Or your morning donut. Get both and throw out the one that you don't like. You can't get a straight answer when the comparison is so indirect.
