Pure And Ethereal: Which Is Better?

So while I am reading the forums I saw someone saying ethereal is better and some say pure is better.

So which is better? I think pure is better since it has rly high spell dmg %. I think that ethereal is better if you have some shit pures like 200% spell damage.

What do you guys think?

 

You're pretty spot on. A bad pure can be trumped by even a mediocre ethereal. But you'd have to have a pretty good pure to make it worth the amount of agi put into pure, which could be put into intel and other aspects for a really good spell build
