With Apple, you get a walled garden where Apple controls what apps are allowed. The apps are high quality but developer control is lost. With Android, it's the "wild wild west" where anything you want to create can get sold. And it shows. I see the new apps each day for Android and most of it is pure trash. Honestly, how many bikini apps need to get released each day? The upshot here is that anyone can create anything and sell it for Android. There is always a tradeoff.
