Well they are almost the same as his brother's Lucifer's which include:
Lucifer is omnipotent, he can create his own universes on a whim, create life and create entire concepts like 'Time' from scratch.
His power is incalculable. He stood on ground zero of the demiurgic explosion, the explosion that could wipe out a multiverse, and didn't even get a tan.
The only thing he cannot do is create his own multiverse alone, he needs his brother Michael to do that.
Only his brother Michael is his equal in power, and only God is superior to both of them.
But the power Lucifer likes to use most is his brain, his devious bastardness allow him to defeat gods even when he is mortal and powerless.
Taken from here
So I say that Michael wins.
