Going through Watch_Dogs (currently at the start of act 2) I've mostly been sneaking around and punching people unconscious to deal with enemies and gang hideouts. However, this has become progressively more difficult to do so without being spotted, so I've started to consider to shoot hostiles with the silenced pistol one by one until they're gone.
I am wondering though, does engaging in non-lethal takedowns net me more XP than just shooting them in the face? If so, how large is this difference? And does it make a difference if they know you're there or not?
