My experience is that they try to move you to streaming if you search for disks, but I have both for my account. They really push the streaming service, which I understand is because their profit is way higher without the physical disk overhead.
I would totally switch, too, if 99% of everything wasn't missing from the streaming service....
I get a lot of "suggestions" for things I've already watched (they love the "watch it again" recommendation under the assumption I'll probably like it because I liked it...), and they don't let you filter out things you've already watched, or things you never want to watch. Instead all you can do is try to train their recommendation system and hope that it actually has some kind of meaning.
Worse, their "new releases" section provides a list of everything released in the last $@#NNNANAS ago, instead of whatever was added in the past several weeks, sorted by week. They are deliberately making discovery difficult, which gives the impression that they are trying to disguise a shallow pool of movies.
Still, they are one of the few services that provides the kind of streaming service that I'm actually willing to pay for - a service in which I pay them, and they show me movies. This is far superior to the BS system that hulu has in which they show stupid ads on the free service, which is fine because you pay with your attention, or you can pay them and watch the stupid ads on your phone or TV, too. There is no option where you are the customer instead of the product.
