Ixlimor or vergumkaar

I was supposed to post this morning but got sidetracked, anyways: this morning I pulled a sole sacred I had and managed to get my due leggo, now the question is who do I focus on.

They both have the one buff I have been looking for(increase Def) with one have an ally protect on the same skill.

Honestly I want to go with the lizard faction frog since I already have a burner on my team in Geo and I think having two would be weird, what do you guys think.
