The truckers hitch lets you get a lot more
tension on the rope and is much easier to adjust over time too.

A truckers hitch offers no more tension that a looped rope an would
offer less if the single part of the rope was on it's strength limits
(compared with two parts).

er.. I think he is correct!

I never learned to do them but my father was an adept.

You gain more mechanical advantage by doubling the final loop.
Potentially x2 but some extra frictional losses.
