Team Mythos for the win.
To be perfectly honest, the 40K pantheon is rather weak, compared to the products of an imagination fueled by a mixture of Pulp stories, horrific nightmares, hydrophobia and almost hilariously outdated racism, even for its time. There's a core of terrible earnestness in Lovecraft's Mythos, whereas Games Workshop's baby reminds me of myself when I used to obsess over poorly conceived D&D campaigns.
"Oh, um... That Evil God's name is... um... KHORNE! And stuff! And he... um... needs blood! BLOOD FOR THE BLOOD GOD! Yeah! Yeah, that sounds badass. Probably..."
Azatoth and Shub-Niggurath are where it's at.
Also, as someone else has so aptly explained through a nifty 'shop job; Khorne?! That's the dumbest name ever for any god!

I cannot take that guy seriously. With all due respect, 40K fans, I'll give the Imperium a shot when I won't feel one of your mythological concepts is Cap'n Crunch's long-lost cousin.
