Iron man vs Superman vs Batman vs Green Lantern (Hal Jordan)

I was hoping to find out who would win but i can't seem to find people who post there opinions with good support to back it up i hope it's different here.
Rules:
It's a random encounter morals are on for one scenario.
For the second scenario morals are off, and it's also a random encounter.
Both scenarios take place in a city, (i.e. New York).
Iron man is in his current, bleeding edge armour.
Batman is Bruce, not Dick.
