Enchanter robe choice

[Arterian]

I'd like to hear some arguments on what robes hold the most value for an enchanter. I've been rocking an Ishva Robe for the cha, but I find the stats lacking otherwise.

It seems Tolapumj and Froglok Bonecaster's are likely better overall.

Obviously we can assume Insidious to be BIS or near it, but for those of us not able to easily get one, let's leave that out for now.

Thoughts?
