Batman's the best in the DC line-up, but it's hard to compare across genres and comic-universes. If you're going for pure 'awesome' factor, it's hard to compare an ongoing runs-forever comic against characters from limited series that have fixed time-frames and hence get to run a full character arc. To pick one that everybody knows as an example, say, Rorschach, where he initially comes across as completely nuts - he's what Senator McCarthy of the McCarthyism era would be if he was a crime-fighter. Then it goes on and he becomes even less likeable and even pathetic (when it's revealed that the father he constantly glorifies was in reality a violent alcoholic who abandoned him as a kid)...but slowly the reader gets to see where he's coming from, until at the end (or close enough, when he gets killed) he's the only character that's anywhere close to being morally 'pure'.
Batman can't have that kind of character arc because he doesn't get to have a proper 'beginning, middle and end' to his story. Even with Bruce Wayne currently dead (well, zapped by Darkseid back to the stone age) and Dick Grayson having taken over, the elements of the character stay constant (he's still an orphan avenging his parents' death - ok, he's a lot better adjusted than Wayne's Batman, but with Wayne's son as the bitter 'father-just-died' new Robin the overall mood is still similar).
