I went back and looked up those fonts.
Atkinson Hyperlegible looks thin and spidery to me. And it has waving legs where it needs to be straight (notice on the "q" tail). At least on the photos I could see.
The Open Dyslexic font does remind me of a learning to write font. I would find all the extra odd thicknesses scattered in the letters to be very distracting. It needs to be uniformly thick, so you aren't stopping on every single letter trying to guess what it is.
I have enough trouble with constant movement and things not looking like what I expect, that I wouldn't likely read something in either font.
The most difficult thing about accessibility is - what helps one person will hinder another, and even completely stop some people.
How do you choose what to use?
This could be a good way to expose people to options that are available, that may work for them, however, don't expect it to work for everyone.
Good luck!
