I'd base it on content you're doing and the problems you are experiencing. If healers are having problems keeping you up then you should probably go for EH, but if DPS is out threating you you should focus on threat, and this can vary between fights. Imo you could use both and swap out as needed, use the axe for threat and the sword for EHP, put like mongoose on the axe and blood draining on slayer of the lifeless, however I would recommend trying to get the weapon from ToC5, as it is probably better than both of them.
