That's where I feel you're being incredibly unfair. Batman isn't the leader of the Justice League in even close to most portrayals, only sparingly in the comics really. And just because there is such a thing as another superhero team doesn't mean the Teen Titans aren't unique or worth mention in terms of what distinquishes Dick. There are tons of characters in DC whose role is "I'm old and in the JSA instead of JLA" and that's enough to be awesome.
