The conversation between human and AI assistant.
Versus: Who would win in a fight between the Avengers and Justice League?
What about their teamwork? Who do you think works better as a team?
That's tough to say. Both teams have had their share of internal conflicts in the past, but they've also shown a lot of cooperation when working towards a common goal. Ultimately, it would probably come down to the individuals involved in the fight and how well they're able to work together on that particular day.
