The Avengers and the Justice League are in their shag carpet covered 70's vans when they hit into each other. They get out and being the road ragers that they are instantly start fighting one another. Keep in mind the people that are fighting are only the ones listed below, and do not have any special powers aside from their regular powers or inventions (Such as Iron Man and Batman). Assume no one brought Kryptonite or a Yellow ring or other hero weaknesses.
OG Avengers (according to Wikipedia)
OG Justice League (again according to Wikipedia)
I vote for the Justice League. They have more people as well as having a better line up against the Avengers. Considering that Martian Manhunter could easily disguise for a sneak attack, and Ant-Man and the Wasp could be killed easily by a simple mistake.
WHO WOULD WIN?
