It's not about whom is stronger, it about whom  or what can kill whom. Demons can only be killed by Angels (And other supernatural beings with magic like demons, and maybe gods and fairies), spells from the Demon Tablet, the Colt, the Ruby's Knife, (I think I covered all the basic stuff). The only exception is the Leviathans, and if they use the Black stuff that, they use to kill angels, it is still different than super strength, But, look at this way. An Alpha might hold greater phyiscal power than a Black eye demon. But, it's more possible to kill them, than a Demon if you aren't or don't have a weapon that can kill them.

As for Dragon, Eve in Bobby Hunter Guide stated that she made the, five Dragon swords to prevent them destroying all her other creations. The Jefferson Starships, have like no standard monster weakness, or flaws. (Except, the eye id method you can use for Shapeshifters.) Also, like she said they can spread through an entire town, in less than a day. She just wanted, a powerful new race, to protect her while on Earth, as well as make all souls go to Purgatory. The Dragons, have only one direct and realistic way of killing them. A Dragon Blood Blade. Jefferson Starships can be killed, like a Vampire taking the head off.

Inshort, somethings have more common methods of killing them, but are stronger. While, others are phyiscal weaker, but are harder to kill. Meaning there are too many factors.
