After using both weapons on all MP's and PVP, I have come to the conclusion that Manticore is superior to Calamity. Manticore reigns supreme in terms of straight DPS; it is simple and effective. Although slower in attack speed, the damage output is double that of Calamity.
Calamity is neat in terms of faster attack speed, hatred regen, and Marked for Death perk. But that to me is just a bunch of smoke and mirrors. My kill speed is slower although I do gain discipline faster with Nightstalker; my survivability is lower because monsters are not dying as quick as when I use Manticore.Yes, I can permagloom with Calamity but why would I need to when Manticore would just simply eliminate the monsters before they can kill me?
In PVP, the edge still goes to Manticore with the exception of a few matchups, but this can develop into a thread of its own. Manticore once again shines in terms of pure DPS, killing enemies before they get the chance to kill me or running away before I get the chance to kill them.
The point of this thread was to share my experiences with both weapons and also gain the communities feedback and experiences regarding both weapons. Feel free to add any insight or if there was anything I missed in my opening discussion. I am looking forward to hearing your responses!
