It is. T2 drones only give better DPS. So it wouldn’t be worth using medium drones before changes. But you imply that isn’t the case. Depending on hull, put some drone application mods. Keep in mind that faction drones have decent tracking bonus. But since gila don’t have any application bonuses and it don’t really have any issues with hitting frigates (with drones) this seams to be borderline of placebo effect. Due to small drones faster rate of fire. While medium drones move slower and have lower rate of fire. Giving effect of being sluggish.
Pick one missions, site, anomaly, whatever. Start a timer and run one instance with only light drones and second with medium drones. Compare times. You should get general idea what preforms better in content you do.
tl;dr just test it yourself ans there is way to much variables.
