Superhero fans generally like Nightwing and most consider him to be the greatest Robin to ever wear an "R" on his chest. He's also favored since he's the first successor of Wayne of all the Bat-Family members. However, despite all of that respect, fans get riled up whenever someone sides with Dick Grayson in the Nightwing vs. Batman debate.
The purpose behind making a Version 2 is to surpass Version 1, but despite this logic, many people still think that Dick Grayson (AKA Robin/Nightwing) is still lesser than his mentor, Bruce Wayne. While fans have built Bruce Wayne/Batman into this god-like figure, one can still argue why Dick Grayson is better than Bruce Wayne.
Batman is indeed an impressive martial artist and tactician, but could he be overwhelmed by Nightwing's superior athleticism and improvisation? Batman is a shrewd detective, but wouldn't he be an even better investigator if he had Nightwing's people skills and charisma? Read on for more details and a full list of reasons of why Nightwing is better than Batman.
While Batman has been involved in several big name superhero groups like the Justice League, Grayson is still more likely to get Most Valuable Player honors from his peers. Batman's off-putting personality, independent streak, and insubordination make him hard to work with and he easily gets under the skin of his teammates. Batman usually orders people around and works above or around his allies. This usually achieves the main goal, but Batman's methods instill unnecessary conflict within the group.
Nightwing, however, has got your back. Whether it's as a Titan, Outsider, or otherwise, Grayson is able to work alongside his teammates. He boosts their strengths and makes up for their weaknesses without belittling them. He doesn't think they work for him - he knows he works with them.
Dick Grayson is in the rare and fortunate position of being a kid sidekick who evolves into a veteran vigilante in his own right. This makes him the better mentor to teen crime fighters who are fresh in the game. While Batman did give Grayson a solid foundation and training as Robin, Grayson can now take youngsters under his (Night)wing, knowing firsthand about the struggles and stresses of being a young hero. He can take the positive aspects of Batman's rearing while eliminating the negatives he had experienced. Grayson is such a valued mentor that Batman's own son, Damian, admires him over Bruce Wayne.
In Infinite Crisis, an older Superman from another dimension tries to explain to Batman that he's joined up with other off-world refugees to replace the current world with his own. Superman argues that his alternate world was kinder and less dark than Batman's current one, and that replacing the old with the new would make everyone be better versions of themselves.
Batman counters with a piercing question: "What about Dick Grayson?" This makes Superman hesitate because... Well, Dick Grayson is a consistent, constant beacon of goodness across the Multiverse. Superman realizes that not all people from Batman's world are corrupted. It also forces Batman to self-reflect and strive to be a better man. In short, the truth of Dick Grayson's goodness and ideals extend across multiple worlds.
Batman doesn't have "friends," he has "allies." Sure, there are times where he is "super friends" with Superman and Wonder Woman on occasion, but he never just casually hangs out with his peers or even members of the Bat Family. Yet when Dick Grayson walks into a room, the party cheers.
Nightwing's friendship with the rest of the Titans, Outsiders, and the rest of the DCU, both individually and collectively, makes him a healthier person overall. This also makes him a better crime fighter since he has other perspectives to draw from. On top of that, these friendships make Nightwing's allies and teammates fight harder and better due to their emotional investment in him.
