Great post! I like this theme a lot and you made your points clearly. I always love to see Batman written as a master strategist. Some writers give him the ability to out-fight everyone, but I'd much rather see him with the ability to out-THINK everyone. It helps keep him in the realm of humans rather than superhumans.
Also, in terms of sheer badassery, *my* Justice League is the JLA from the Morrison/Waid/Kelley era. The best stories from those runs forced the JLA to be greater than the sum of its parts.
