Which should I level up first Thor or Uraeus?

Back on to the original topic of Thor vs Uraeus:
Both have been out for close to 2 weeks now. I know thats not enough time for most to max and form the best opinions, but I am in this scenario and having a hard time deciding.

I have Thor to 3-60 and will have him at 3-70 shortly. Today, I just pulled Uraeus (bonus for me because I usually never get the HotM that I really want!)

I would like to see if either of these would be a good hero for defense but also fit in a yellow stack for offense. Rana+18 is my current def yellow. When I first pulled Thor I was super excited to get him and put him in defense, only to realize he probably isnt best suited for Def. Uraeus, being a sniper could work in Def because damage is good and my other defense is almost all AoE.

As for yellow, I have Jackal +20, Gulli+18, Joon +9, Rana +18 and Gazelle+9 (also have Ranvir+2 and most all 4*yellow). I would probably drop Rana in most scenarios for offensive stack.

Bonus, I have a ton of Sorcerer emblems to spend and 0 Fighter emblems.

So, is the general thought that Uraeus still might be better as the first one to max?
