In my opinion, Lucifer is at least powerful enough to hold his own against Micheal, but ultimately the elder brother would win. Micheal is indeed the most poweful archangel, but by not that much compared to Lucifer as he is extremely powerful in his own right as well. Hence why I believe Lucifer would put up a good fight as I highly doubt Micheal could defeat him easily as Castiel had done to Raphael in "The Man Who Knew Too Much".
