So far what I have enjoyed most is wind main. I use 2 formations
Sage naruto / kurotsuchi/ wind / onoki
You can switch kurotsuchi with Iruka or 5 large summit temari for higher damage on naruto
I've been running lightning tiger summon, low to high chase and either gust Jutsu or reset.
With fire mains I tend to use sage naruto/ kurotsuchi/onoki with dog of hell and high to low float chase. You c*e seal for control of specific targets, if you really want to control everyone you can swap kurotsuchi for shikamaru to control/sleep 3 targets a round.
Fire is great for control while wind has potential to make naruto a god.
With the wind formation I kill everyone around my bp round 2 with Jutsu and lightning mains will literally have no chance.
Also as a side note I'm interested in trying onoki with earth main and running it with gnw kankuro but haven't tried it yet.
