Best Pillow for Apnea Which One Is Worth It?

I am in the market for the best pillow for apnea and I want to get some advice before pulling the trigger. My main priorities are comfortable sleep, good neck support, and keeping a proper sleeping position. A pillow that works well for side or elevated sleeping would also be a big plus.
After reading expert reviews from trusted sources like Sleep Foundation, Healthline, and Good Housekeeping, two types consistently stand out as top options:

Coop Home Goods Adjustable Loft Pillow
(https://www.amazon.com/Coop-Home-Goods-Memory-Foam-Pillow-For-Side-Back-Stomach-Sleeper/dp/B0BGQ8VWRJ?th=1)
It offers adjustable fill, good neck support, and lets you change the loft based on your preferred sleeping position. I have seen a lot of praise for its comfort and versatility, especially for side sleepers.

Elviros Cervical Memory Foam Pillow
(https://www.amazon.com/Elviros-Cervical-Shoulder-Ergonomic-Orthopedic/dp/B0833V68BJ?th=1)
It has a contoured design that helps support the neck and keeps the head in a more stable position. Many reviewers mention its supportive shape and comfort for side and back sleeping, though some say it takes a little time to get used to.
I am having trouble deciding which one would best suit my needs. I mostly sleep on my side but sometimes switch to my back. My budget is flexible, but comfort, support, and overall quality are what matter most.
So which one would you recommend? Any advice or personal experience would be appreciated.
Thanks in advance!
