yes, all depend on the build design. Even some drones can be less effective in raw power, they are better than the best in matter of design with parts available.
If will look at raw power, then Selfish Guardian but that power comes with a price tag of consuming HP, but it is a drone that work at any range. Solar torch can be the second best limited on range but not HP consumption.
Like STAR mentioned, it is about design how effective will work the drone in use.
