That all depends on the base layout and what your attack plan is.
I have used 4EQ with success plenty of times when raiding, and a few times in war.

It can also now be useful to use 1EQ with 2 lightning to take out an AD, leaving you with an extra lix spell slot, and actually making dragons viable on some TH9 bases.
I actually tried this successfully in the war we had ongoing at the update. OK, I still only got 2 stars, but our three oter attacks on that base had each only got one. And we won by three :)
