The easiest way to summarize Luftrausers is to call it the Hotline Miami of dogfighting games. It's incredibly difficult, but it's really good at sinking it's claws into you to keep you launching your planes onto the battlefield. It's a game that's really easy to binge on, but since it naturally comes in bite-sized battles, you might get a bit more staying power if you get it on the Vita and play it a couple hours at a time.
