There are a lot of similarities.

However, I don't think angels or demons can become stronger. Castiel got stronger, from normal angel to seraph, because of God.

Crowley is a crossroads demon, but I think his power level never changes. Sure, he rose through the ranks and became King, but he ruled through fear, not might. Crowley has survived numerous deaths simply by being intelligent and cunning.

Also, we don't know who took over Hell once Lucifer was imprisoned in the Cage for the first time. We know that at some point, Lilith got trapped "neck-deep" in the Pit, and Azazel took charge. When God left Heaven, Michael took over without question, and he remained in charge for eons.

To say Lilith took charge of Hell after Lucifer is speculation, but I do agree that the two systems do mirror each other.

Not to mention, right now, there is no known ruler of Heaven or Hell. God has left again, and Lucifer is who-knows-where. The demons also don't want Crowley back.
