Apples and oranges. On iPhone, user-mode exploits may remain sandboxed, unless they break from sandbox too. On jailbroken iPhones, that last step may be pre-made for them. On Android, user-mode exploits may remain sandboxed too, unless they break from the sandbox - same as iPhone. On rooted Android devices, the last step may be pre-made for them. You can not compare stock iPhone and rooted Androids - just like you can not compare jailbroken iPhone and stock Android.
