That’s a tough one. I have both.
If you want a specific movie, Amazon has more.
But unless it is fairly recent, you’ll still have to buy it a la carte usually.
I have to say that YouTube is getting some good documentaries lately. I’ve stopped my “Curiosity Stream” and “Great Courses” as there are so many good ones on YouTube.
Just saying...
Netflix by far. Less expensive and one does not have to buy them. Amazon has very little streaming for free that one would want to watch that cannot be gotten elsewhere.
I have nothing to add, just want to comment.
There is so much out there, in terms of cable/satellite TV, along with DVDs and services such as Netflix, sites such as YouTube and Hulu, well, to me, it feels like there are endless numbers of choices of what to watch.
I don’t watch much TV or movies or DVD. But I get the feeling that when I’m retired, I will be overwhelmed with so many choices which modern technology has given us.
