The Hawk Moth II is a great little beast, especially the MML version. The utility you get out of it is amazing, and it's a good case for mixing different ammo types. A VTOL that can spread Smoke of Thunders and then follow through with live warheads is good in my book. The utility of the turret is also a bonus, allowing a bit more flexibility in how you attack and/or planning a fast getaway.
Cannot reccomend it enough
Well, save for the sniper version. That thing's hideous and I wouldn't touch it with a HV stick
