Fury is pretty solid when it comes to survivability.
Lots of self-healing and damage reduction with the right build and spell reflect is amazing with a short cooldown.
I solo most rares in Korthia as Fury, though I never played demon hunter so I dont know if they are better.
what is it you intend on doing ingame? PVE or PVP?
Personally i’ve never enjoyed DH playstyle but that’s why i’m in the warrior forum i guess… IF it’s PVP you’re looking to do then Arms Warrior is by far superior to DH in terms of survivability and utility it provides to your arena partners.
PVE - I find current Arms very boring and rage starved quite often where as Fury is a lot more going on but everything outside Rampage and Execute the spec feels like slapping people with wet noodles.
I guess DH has Darkness which is very nice for M+ but Warrior also has rallying cry which is a good option as well.
End of the day the old cliché will pop up again, play what you enjoy more as each person is different.
