Up until recent times, I would have said Netflix because of it's assortment of options to choose from, but they have cancelled a lot of great shows that I wanted to watch so for me HBO Max is my favorite streaming platform because of it's spread of critically acclaimed shows and movies. It seems as though HBO Max has more options to choose from than Netflix. I don't have to rewatch the same shows over and over because there's nothing else to watch like how I would be when I primarily used Netflix. I can find shows that interest me on HBO Max.
