Hard to gauge his durability. Nothing hurt him except metal from his own ship but it is not as if he was facing superhumans with a magic sword either. He doesn't need to dodge bullets at least and can casually fly through concrete buildings.
Speed I think they are comparable.
He didn't have all that many strength feats either to put him in her tier.
He doesn't have superman level heat vision as it took a few seconds to melt through his dad's head.
He however can fly.
He will probably lose if he doesn't take her seriously and fly to begin with. Perhaps stands a chance if he flies and she can be injured by his heat vision. Also he is not full grown. Maybe give it to an adult version.
