One crucial difference, please:

Ambisonics is a spatialization technique.

So called "5.1" is just an arrangement of speakers. It is no more than
that. What you don't like is the way the content creators are using that
particular arrangement of speakers to render their music (or effects, or
whatever). For that they use one or a selection of spatialization
techniques of which Ambisonics is just one example - the subject is
actually quite complex. I imagine most use just a variation of amplitude
panning or something similar. For the same arrangement of speakers (5.1)
you could use Ambisonics or any other technique.

So, comparing Ambisonics and 5.1 is comparing apples with airplanes
(oranges would be too close, they are both fruits). Very different
things.
