HD - as far as I'm concerned even since it all came in the odd hug and reassurance is still very much required.
CISM can be absolutely excellent - I've seen it in practice really help people, however it is down to the person defusing to do it well and appropriately.
People do react differently (or in some cases not at all!) so one size can never fit all.

P.S. Don't worry Gonzo, I'll still be there to help pick up the pieces when you do fall apart.
