Help a brother out? Recommendations?

Jag Panzer - Decade and Mechanized Warfare would be your best bet.

Dimmu Borgir - I like the slicker produced stuff better so Enthrone Darkness Triumphant, Puritanical Euphoric Misanthropia

Morbid Angel - Alters Of Madness, Covenant. I'm surprised no one mentioned Domination. I like that one as well.

Don't really know too much about the other three.
