Depends on if you need the full auto spray-n-pray option or more precise shooting.
(If y'all were curious why the ammo rules were changed for droneguns, it was a few things. The size of the frames was usually small enough that 250 rounds of belt-fed ammo didn't make much sense, but it was also to give a bit more diversity, so sniper-style shooters or dartgun drones would be an approach outside of MOAR DAKKA. options are good, and it encourages more variety of play. At least, that was the design goal. You'd have to tell me if that worked or not.)
