I follow Ryans channel and I thought his episode covering the use of the USS Colorado in the search was informative and un-biased. He did mention Gardener Island so I give him a thumbs up (while also appearing skeptical on the latest sonar image).
I've been following him for a while as well and really enjoy his channel. From what I can tell he appears to be pretty well respected in the curatorial world. So to have him say "I have no doubt she would have found an island" I would call a win even if he got some other details wrong.
