My mother quit Netflix jz and bought an abo on Prime, just looking for arguments to persuade her, do you have any?
Netflix offer a clearer and better movie selection and you can look at several devices, what you can't do with the other one
I have both streaming services, but I honestly think Amazon Prime is more practical. For the reasons that you have free shipping on Prime items and they arrive within 2 days. You can also use Amazon Music, although there's no brand new music, but the music is still good. But one downside is that there's content in Prime that you have to pay for. (Sometimes the last season of a series, which I find really bold…) But Amazon is just a company that sells products, which they also show here. In the end, both services have their advantages and disadvantages, because which series you like to watch depends on each one individually.
