JLA VS avengers scenario

which one of these two teams would benefit our world the most? which one would make it worse?

just the characters come. standard everything

the same team of jla/avengers from the crossover event

Probably the JLA. They have a good combo of speed, intellect, magic, and power.

Thor is everything you just named plus interest. I'm saying the avengers .

The world would benefit from vast technology from the New Gods. Orion has everything Thor does, and then some.

Orion was in the crossover?

Yes. Most of the JL were at one point.

Its a toss up.
