Leviathans are older. Eve is younger then the leviathans, however she is more powerful, she was the boss of purgatory, which probably was gods way to keep them under control and was said to be the creator of all the other beasts, also eve is more powerful then michael and lucifer when she met Castiel, he couldn't even use his power and she said to him she was older she knows what makes angels tick. Although I think it's a bit dodgy that she's stronger then michael and lucifer she probably is.
