Archguns, Whether In Archwings, Necramech, or In Your Tennos Hands Which One Does It For You?

I really enjoy Archguns, not just in Archwings, but also attached to my Necramech, and even when I use it on the ground.

It's really stupid fun to just air drop a giant fucking cannon or laser or something else and just blast enemies.

Which ones are your favorites and in what scenarios?

Looking for advice as right now I'm just rocking Ayanga on the mech, grattler on the ground, and dual decurion in the skies

Ayanga cause explosive and it just reloads so quick in the mech Grattler just blows things apart and decurion I'm honestly not sure why I just liked the dual wield I guess?
