Just wanted to make a small correction on this weapon. It's actually DMG:+19, not 18, Which would make it a shot better than Destroyers DMG wise, and with only 1 higher delay that Destroyers(+48) plus the +9 Eva/Acc is great in my oppinion, It's dang near like wearing a Scorpion Harness on your hands, and of course, the Subtle Blow is always welcome. This is just an awesome weapon.. But I know what you're thinking "Don't forget the Enmity, that's what kills this weapon for Monks." And I agree with that somewhat, the +9 Enmity is a real turn off for me, being 75monk. It's not as bad as it looks tho. In EXP/Merit pt, I believe I'd go with Destroyers, but for soloing/Zerg style fights(gods etc..) This weapon is amazing. And with that said, lets get to the facts...
Hades Saint +1 = 5-10Mil depending on server
Destroyers = Free (At most a few K seals)
So that pretty much says it all right there. Destroyers are more practical, and is a must have for Monks. If you're just that rich and can blow 10mil on Hades+1, go for it man, it's a great weapon to have for certain situations, but in the end, you'll still be using Destroyers too. So i'm not saying either one is better, it all boils down to what you're doing and what your budget is.
And that's my $2.25 worth :P
