It really depends on the base for me.
I use a GoGiWi(He) army in wars for 3 stars against TH9s. I take 4 EQs and 2 Rage spells along with a Poison, it works out quite well for me. The biggest thing with EQ spells is they also do heavy damage to the buildings around them, so if you take out some core walls and hit the TH and CC as well, maybe even an XBow or two, that right there is a lot of HP taken out of the core of a base.
