Yes it is

As long as you don't run out of ammo while fighting

Clans also lack some early dedicated AA, not that it matters much right now, since the Sparrow does pitiful damage and the VTOLs are easy enough to bring down with other weapons.
Still, once the Corsair makes it in, it'd be nice to have an AA platform that isn't as expensive as the Huit (I'm guessing that the Corsair will be a tad cheaper than the Sulla) and I'm not really sure which 'Mech/Vehicle could fill that role.
Maybe the Svantovit, with an AA loadout doubling as cheap BA deterrent (which the Clans don't have right now either)?
