bloody mary for sure (late marignon). Fire and lightning and blood and astral, and I love their theme of corruption by Ulm's Illuminated Order. Plus some awesome national summons and perhaps the 2nd best blood sacrifice in the game.
Bogarus, Sauro and EA C'tis are definitely close favorites too.

I have no doubt whatsoever that Late Marignon are the strongest at blood sacrificial, it's one of the things that makes the nation so grossly unfair in some match ups.
