Although the Banshee excels as a ranged Warframe, it also performs excellently as a crowd control Warframe using its abilities Sonic Boom and Sound Quake. These abilities are highly effective against the swarming Infested but work against the other two factions as well.
Moas are extremely susceptible to Sound Quake, and generally works well against other Corpus enemies. Decent against Grineer, but worst of the three due to their innate high armor.
Remember that Corpus & Grineer tend to do less swarming, though the stagger effect will help team members deal with enemies more effectively.
As of Update 13.3, Silence is a radial ranged effect that moves with you and Sound Quake is togglable and will consume energy per second while active.
