They've done some research on it.

Heph is the best middle ground imo. It can Telestomp, and easily aquirable.

Urdar's has Crushing blow and a real nice big attack and huge hp pool, great for spamming blood boil.

Spear Maidens from Act 5, have the best dps, but are the hardest to get. Least tanky, but it deals the most damage as it uses Jab which turns 3 autos into one hit. I saw somewhere someone mention it does over 100k in one hit.

Always go for cursed, and then the aura really depends on you, Might aura is great if you prefer cure merc. I prefer Cold aura as it slows down everything.

I’m really liking the venom lord style demon. Looks cool, great aggressive ai. Ranged fire attack. Amp is always up. Great tank too.

Any demon +fanaticism + cursed. I prefer Venom lords because they are fast and cool.

I don't buy the hype on Spear Maidens. Jab is nice but they've been popping like Emilio. Even a regular Diablo chunks them sometimes, lasted <5 seconds in Colossals. I don't think they're worth it at all without a heavier investment to the Demon tree.

Hephasto w curse and fire/lite/cold aura.
He is easy to farm, tanky and procs aoe curse.
Sure there are better maybe spear lady or lister but farming them is way longer.

Had p3 vile lancer farmed with cursed TZ method thats died to nothing, using about+14 all skills.
you can gear swap to all +demon skills for the bind

lancer + heph also move after you tele which I prefer
urdar has the most regen but i'm not sure it matters because engorge exists for free

to put some numbers to it
heph has 94k hp in p1 / 423k in p8, with 50% dr and 0 regen
tz urdar has 30k hp in p1 / 134k in p8, with 55% dr and 2.44%/s regen (frigid/acheron has 1.15x hp and 75% dr)
tz spearwoman has 14.5k hp in p1 / 65k in p8, with 33% dr and 1.22%/s regen
matrons spearwoman has 53.5k hp in p1 / 241k in p8, with 33% dr and 1.22%/s regen
then you get blood oath which should be maxed on all builds anyway so its ~12-16x the base HP, and another 1.74x the total HP from battle orders

With BO active, my Gulzar has 4000 hp / 0% dr, and my urdar named Blade Blister has 4250000 hp / 91% dr
At some point I think you can reach such astronomically overkill numbers on demons that even lower HP mobs like spearwomen are just effectively immortal. Maybe on a blood boil build being incautious and tanking ubers its possible for her to die where an urdar can't (but heph absolutely would because of his 0 regen). On a non-boil build with max blood oath they should all be immortal in all scenarios, let alone an urdar that regens more damage than any pvm monster in any scenario can possibly deal, hell he could probably tank echoing strike warlocks in pvp for many hits if you didn't let them hit you

To be clear, I think that you need to be actually spamming boil enough to get your monsters to sub 5% hp from you nuking them to a sliver of health before its even possible for them to die. Blood boil won't cast if they're below 5% hp, but they could regen slightly above it and you drop them from 5.1% to 0.1% hp and on the same frame they take some massive spike damage, yes maybe they can die. Requires obvious human error and ridiculous monster dps because even 0.1% of that 4.25 million hp is still more HP than my gulzar has at full health, and that urdar is regenerating over 100k per second and has 91% dr and casting engorge instantly restores 3.3 million hp

its why echoing strikes builds can get away with using hephasto even though he has no regen and most players aren't binding engorge, because millions of hp means it just cannot die

if you bind demon from terror zone it has higher lvl/auras?

Yes, monster level is baked in when cast. So bringing a hell monster to norm it'll one shot stuff.
What's baked in: monster type, name, level, P1-8 HP, affixes, aura type, TZ affix added for normal monsters in TZ (not minion/champ/unique)
Whats recalculated each game at start: +damage, +% damage, +% hp from mastery/bind/blood oath current level

I'm surprised Matron's Den Spear has that much HP, given that the zone can't be TZ I figured the higher level would be better. Though FWIW, it was a Matron's type(p1) that I popped in <5 on Colossals so not like it matters.

I'm sure Blood Oath is fine I just don't see the purpose for Echoing when Heph is already immortal. For me its Urdar if I want specifically want crushing blow for bosses, or Heph. I'd love to make Spear work because its a lot of fun watching her zip around.
