Green Lantern Vs Iron Man

The strongest incarnations of each in a battle
and
normal iron man vs kyle

Tony's crafty as hell. Kyle SHOULD win, and obviously has more potential power, but he's still young. If he slips up, Tony could feasibly sneak out a win.

what about the first scenario? what the most powerful version of each? thorbuster iron man? iron when he was like dr strange? and what about gl? is ion or parralax the strongest version? and who wins between the strongest of each

ion would beat any and every Iron Man.
