I think it's funny how we, the living, are talking about whether death occurs or not even before the jumper hits the ground.
To me, this question is the same as "How would death feel like?"

Answer: Nobody knows, because do you know anyone who has come back from death to explain it? I don't think so.

And people can only give assumptions at most. Unless someone knows how to use an Ouija board and find a willing interviewee....
