Devils are probably the single best value summons in the game. Throw an Arch-Devil in later to lead them, buff him up with ethereal and damage items, and you have a flying, 3 map move, monster army. Devils have about 35 hp, 15+ attack AND defence, and still decent protection. Very good damage. They just about wipe out anything that isn't top drawer in power.
I'm not all THAT fond of soul contracts. Eventually, yes, they do pay for themselves but at 12 turns its not terribly fast. Contract a strong commander and hope he can defend himself but this often means placing an important hero in great jeopardy. Contract some crap hero and he may well die before the time when the contract pays for itself with devils.
Infernal Forces is WAY better than a Soul Contract, especially if you have a high blood caster. I think its 7 Devils free +1 for each Blood magic above five. I was getting 14 Devils plus the 20 gImps for only 50 slaves. That is nice

, but its at the top of the research tree and so only for the late game.
Also as an aside, does Marignon have the best blood hunter in the game? The Goetic Master isn't cheap but with 2 blood and being sacred he seems to really rake in blood slaves on hunts. So even if in theory 4 scouts could hunt as well as he could per turn (4 scouts about equal in upkeep cost), he has 2 Fire, 2 Blood, can build temples and labs, and basically just kicks more *** for only 90~ish more. With 10 Goetics i was taking 50-100 slaves a turn. PLUS, Goetics can easily summon Devils.
After testing Marignon Diabolic Faith im might be convicned that theme is the best blood nation in the game. Mictlan is just too much pain. Blood Sacrifice needing temples? Bah!
