Help! Ps5 or Ps4?

as a lifetime xbox user, i finally got fed up (not being able to play the ps originals) and im looking into getting a playstation. I want to play tlou2, ghost of tsushima, spiderman, etc. As the ps4 is around 300$ cheaper, I was gravitating toward it. However, I would like to see what others think about this, is it better just to save up and get a new ps5 so I will be able to play future games etc? Thanks?
