What do you mean with experience? I personally think that "kicking a chair" is easier in the end than tightening a rope manually. Both are maybe the same, it's about passing out quickly but the difference is, full suspension cannot be reversed once hanging.
I'm personally not interested in hanging myself, but if that was the only method I would go with full suspension because once hanging correctly there's no way back whether it's painful or not in the end.
Dunno, but maybe I don't get your question right?
