Ok, so everyone thinks that LT is all power and all this stuff but i think that Lucifer could give him a very good run for his money or even beat him. I will list some feats for you i warn you though SPOILERS AHEAD!
1. Lucifer was once attacked by indestructable (even to him) beings yet he in seconds found there source through out all the world and killed them.
2. He is stronger then all the lords of hell including the endless. For example he speaks to dream about how other lords of hell speak as though they actually have deposed Lucifer he basically talks about it as a joke. Dream is afraid of him in sandman saying he is probably the most powerful being in creation sept for his father (lucifers father) he also admitted to being weaker then him. Destiny wouldnt give lucifers brother a peak at his book micheal said either lend it or i take it.
3. when lucifers father left the universe two trolls got on the throne and took his power, they made a clone of lucifer using a womens memory, lucifer used this to his advantage by using the trolls own power against them in the past when they where not yet omnipatent, and so they died.
4. Lucifer was told to shut the gateway to his own universe or else, he got mad and actually made maybe millions out of that one gateway when before there was only one.
5. lucifer has defeated gods in there own realm while powerless, when he is at full power he can destroy a realm just by being there such as the house of windowless rooms where angels go when they die (not a pretty place)
6. There is a misconception of what lucifer created beyond his gateway well i am here to confirm he made a MULTIVERSE not a universe, this is confirmed in lucifer nirvana though i guess the mistake can be understood since this use to be a hard to get comic but now you can read it in lucifer 11 endsong but yes he is speaking to his gf, and she says you created your own realm, he says i qoute i didnt create a realm i created a totality a multiverse. When creating his own multiverse he needs his brother's energy because its the energy that makes up the universe but lucifer is the will that made the multiverse of his father shaping it into planets, suns and everything even life he had his own adam and eve. When making his own universe he stood ground zero at his brothers explosion of power, the host of angels from the silver city wouldnt dare trying to release his power in an already developed multiverse saying it would destroy everything this is also said again when they are fighting fenris and trying to save the multiverse from destruction after lucifer and micheals father leaves, lucifer and micheal are equal in power sept they do have diffrent powers but lucifer has defeated his brother.
