Black Panther's skill level and ability is what Batman should be (Panther would beat Batman in a random fight IMO). The only difference is popularity pushes Batman into every imaginable situation such that he is forced to complete with characters and situations he should have no business dealing with. This is why you see all the power armors and schemes. His best stories are against street level villains with an occasional splash of "Super". Anything else, is forcing him to sell more comics.
The entire concept of "prep time" speaks to the overrated aspects of this character. You have to force a macguffin in there to somehow make your favorite superhero on par with characters with powers. It diminishes any real discussion of the idea of Batman and what really makes him great.
