I have been using Oyster books for five months. Same deal. Ten bucks a month for all you can read. Just like a Netflix for books.
I just started Bookbub. I like it so far.
Depends on your reading habits and interest.
I read about ten books a month. Many I do not finish if they get boring. Much easier to do when they are free.
Oyster has a 30 day free trial. I have enjoyed it and can cancel whenever I want.

Yes to Amazon Unlimited, no to Amazon prime.

I dropped prime when they increased the price. Apple users are second class citizens on Amazon Prime. Free kindle stuff does not apply to the kindle app on IOS devices and they don't support Apple TV.

My wife spends about $30/month on Amazon and iTunes for her entertainment, mostly from bookbub. It is pretty much all the stuff she enjoys now, so a nice savings for us. Lots of stuff for me, non fiction, cooking, stuff that I would never buy otherwise.

PS: Unlimited means 10 books at any one time. You only find out that little detail when you download number 11. So, don't plan on building your collection. They do make it easy to pick the book you want to get rid of when you select a new book.

In terms of selection, it is analogous to Netflix, which we also use.

We cut the TV cord almost a year ago. Hulu, Netflix, Amazon Unlimited and a lifetime XM Radio subscription are all the news and entertainment we need.

I signed up for the 30 day free trial. I will let you know what I think after I have given it a shot!

I just wrapped up my 30 day free trial of Kindle Unlimited and have decided not to renew.
I read...a LOT; so any and every site/program that offers me free or steeply discounted kindle books is my friend. I've been on bookbub, bookbasset, ereaderiq, hundredzeros, etc for as long as they've been around.
The offerings on Kindle Unlimited are generally the exact same books I'm already getting free (to own, not borrow) from the above website offerings. As others have noted there aren't many bestsellers offered, nor are there many 5-star books. I also don't like being limited to "checking out" 10 books at a time. So many of the freebies are awful that I load up dozens at a time and then sit down and preview them to see which are worth keeping (about 10% is my average on keepers).
As to amazon prime, I wouldn't be without it (and haven't for years). We order a substantial amount of our groceries, car parts, household items, gifts, etc via amazon and the free 2-day shipping (which is frequently overnight) is worth it in and of itself.
We don't have cable, so the Prime tv/movie offerings are what we have to watch other than hulu/netflix subscription.
