i've been thinking about going for chains of honor beacuse its so much more tanky than ormus. should i do it?

if u want stack resis etc yes.

Enigma is better than both.

BUT between the two, CoH or Ormus, I'd say CoH

Enigma > Viper > Ormus > Stealth rw > Cracked leather armor with chipped ruby > CoH

This

4os sacred armor with 4 prubies if vita, sapphire if es, emerald if mb.

if you don't use chainlightning and charged bolt, then ormus is bis
else eni

This. CoH is noob bait, or maybe your sorc needs 200% demon damage?

Depends on your char of course.

If you need fcr, then Ormus or Viper.
Else, Ormus for damage, or Enigma for everything else. CoH is good if you don't reach max res.
Full Tal set is usually good too...

I knew that someone will compare CoH to cracked armor xd

Using CoH instead of Enigma is like using Forti on your a2 merc
