Dragon's Spine Belts

Hi I've done monastery enough times to get 196 rares and the wolves belt havent droped. Im thinking about buying one belt from Dragon's Spine. If it was for my DT I'd get the dark mesenger one but for a Guard...Im not sure. Maybe the 100 of constitution of the black Pharaon belt make the difference.

I like the stats of the wolves one a lot, ¿Do you think the Dragon's Spine belts are better? (without takeing into considration that one is free and the others are cost 196 rares and 10G ofc)

Black Pharaoh has a lot more con but has less armour. I'd much rather the mitigation than the extra health. The rest of the stats are just extra reasons why IMO Dark Messenger > Black Pharaoh to me.
