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.
Charisma can get you far in life and Grayson is filled with it. With his smart*ss personality and charm, mixed with Batman's training and color scheme, Nightwing has the best of both worlds. He can be a terrifying presence to criminals given his association with Batman and his terrifying scare tactics, but he can be a charmer when he needs to gain access to information from other sources or convince would-be allies to trust him.
Batman's method of persuasion is "carrot vs. stick," relying heavily on the stick. Grayson knows that in many cases, you can "draw more flies with honey" by being more personable and compassionate. Combining the two, Nightwing ends up being an effective honey-drenched stick against crime.
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.
