shoud i use paths or keyframes

I was wondering for animating whether i should use paths. Lets say i was creating a jump animation, would i move the object by keyframing the main bone or would i use a path to move the object.

For animating characters use Keyframes unless you´re doing a walkcycle. There it is more comfortable to constrain the movement to a path. This helps to reduce the repeated insertion of the same Keyframes. But with Keyframes for normal movements there´s much more control (for finetuning).
