lets stick to the topic here. both drones in question have limited uses.
here's the thing. there are obviously better drones to use, but since you asked about these two specific drones..... lets stick to these two drones.
if you build energy, use face shocker because energy dmg. if you build heat/explosive, use heatpoint because heat dmg.
another thing you should know is that there isn't really a "dmg" build type for energy, not like heat. so naturally, all energy parts will be based on draining, or regen, or sometimes, dmg and res (but that's pretty rare and limited)
for heat tho, you can have either boiler (as in corrupt light, savagery and stuff) or dmg (dawnblaze, supreme cannon, or other rocket launchers). boiler also goes into pure boiling or cooling drain.
imo, heatpoint is good specifically for dmg builds. heat gain stats are obviously less than energy drains because it does dmg.
NOTE: don't compare with Swoop. otherwise, all heat drones are trash. (which they are, but then again, Swoop is premium)
