Your version is just "two half hitches". The variation is superior and
is called a "tautline hitch". Its adjustable. Its the same knot youd
want to tie a tentpole to a stake so you could tension it later.
Variations with loops doubled differently, or tied with the outer loops
first and the inner loops last are all hitches. The inside-out ones tend
to jam.

Which do you prefer, the aircraft moving or the aircraft bending?

Which do you prefer, the tiedown stretching or the aircraft bending?
But people use chains all the time for convenience, usually bolted to
steel cable which is anchored along the ground.
