[WSIB] Dark Souls 3 DLC or Horizon Zero Dawn

I completed DS3 when it first came out and have since gone back for another play through of Dark Souls 1. I love those games but have admittedly never played Dark Souls 2. Alternatively, I keep hearing good things about Horizon so I'm wondering if I should opt for this instead. Would it be a breath of fresh air after a long stint with Soulsborne games? Is the DS3 DLC worth it or should I put it off until later and switch it up and go for Horizon?
