Well...I might not be too fond of a
blue puzzle piece. Otherwise I'm indifferent to the use of a single puzzle piece.
I admit I sort of like the Autism Society's
multi-piece puzzle pattern.

-I think it is widely recognized and distinctly associated with Autism.

-I see the world as a puzzle and I think many people see
me as a puzzle.

-A
completed puzzle is a
success.
When I was talking about awareness ribbons with my bride she asked me what color the Autism Awareness ribbon was--I liked being able to respond correctly "It's complicated."
(She's
ADHD and I think orange is a good color for
her ribbon--sort of a warning label!

)
I am inclined to like the
gold infinity for "Autism Acceptance" of
Autistic UK. But for Autism
Acceptance, which is how I feel about
my Autism.
And I'm accepting but not overly fond of Autism symbols that explicitly show a spectrum--even though it is a spectrum disorder (it's not the only one, however!). I think another community cornered the market on that color scheme--it's sort of their trademark, isn't it? (And, yes, I know many of my WP posts use a spectrum of colors when I refer to the
Autism Spectrum. My only excuse is I'm an Aspie and I think it is fun to play with the BBcodes.)
I have a dislike of both the puzzle pieces and the colours. While colours are great at representing a spectrum, when it's associated with autism, there is something implicitly childish about their combination together.
Google image "Autism" and have a look at the results. They consist entirely of pictures of children and bright colours. I think there needs to be a fundamental shift away from how autism is specifically portrayed. I actually find the current portrayal of autism right down to the logos to be deeply humiliating and
infantilizing to the upmost.
The Rolling Stones "Paint it black" comes to mind. Even no logo at all is a considerable improvement. Hell, even a logo of a noose is better.
