Statistically, I would guess the body strap version is safer, yeah.

Btw, saw this comment at the Evil Empire talking about OP’s photo:

fun fact: I’m from a small town near this place, and apparently kids did end up in the river from time to time, but there were no serious incidents (btw the rope was actually made from iron, and in winter it would freeze. fun times i guess).
