Which audiobook provider is the best?

Actually, I really like Audible's choice of content. However, it is totally stupid if there's only one book per month for the expensive subscription. If I don't like it, do I have to wait another month? Expect something like Netflix. Content that I can access at any time during the subscription. Which provider is recommended here?

You can return the audiobook to Audible and get a credit. I'm very happy with Audible and the benefits if I want to buy more audio books.

I didn't know how to give it back.
