I've found Mauraders and Mitrailleuse to be the most effective points per res spent if going for pure point value during a BH mission. Defensively it would be the bonnie at 1/2 point.
If resources are an issue, you're doing something wrong (ran out of weak players to bully, maybe?). Mars and Bonnies are the best choice because of their training time, especially if you pearl their training speed and get Magic anvils (although, it's annoying to remove them and put back all the time).
I wouldn't go for Mitrailleuse simply because their training is two-fold: first you have to make gears, then you have to make units.
If one really wants to look at the resources prices, then yes, gear units have a great ration (Duelists, Gunslingers,... not much worse than Mitrailleuse). Or, even better, veterans (but these cost rubies).

I could be wrong and hopefully someone will point that out for all of us if so it's been a long time since I looked at the numbers. :))
Bonnies are a bit below 0.5 points, but not much: 0.475.
The formula is super-simple: basic power points (you see it when you mouse-over power points of a unit in Tavern/Armory/...) divided by 40. No bonuses applied, ever (except exp. bonus in case of exp. events, but that's different). So, a Marauder is 40/40 = 1, a Bonnie is 19/40 = 0.475, etc.
To find out which is the best for the resources or time spent training, one can just divide total res or time with basic power points and aim for the lowest number. If one overflows with rum, then ignore the rum cost of training, since your rum is "free" (you're spilling it anyway). In that case, Chinese drunks can come in play, especially if you can set a trap against someone who always attacks predictably, with the same unit type (in which case, their effective power practically doubles).
