From reading accident reports, it seems that if the aircraft is under control at the time of the crash, ie. being flown to a crash landing there is a good chance of survival and minimal injuries. If the aircraft is out of control ie. stall/spin, disorientation in IMC, death spiral, etc. there won't be much left.

Side note: The media knows nothing about aviation. A Cessna lost power and set down in a mall parking lot over here in NJ the other day. They reported that in instructor and student were on board and "it was not known which one was at the controls at the time of the crash..."

P.S. Good tip about noting anything you touch/move - this is very important to the accident investigation.
