I always add teardrops on vias and the through-hole round pads. The software adds tear drops to every round through-hole pad and via but sometimes I remove tear drops on some of the larger round through-hole pads that have larger annular rings and usually thicker tracks connecting to them in order to improve the copper plane pouring around pads on things like connectors.
