Need help selecting books

What is Product Design - Slack
Product Design Now - Campos
Design Secrets: Products - IDSA
Product Design and Development - Ulrich, Eppinger
Managing the Design Factory - Reinertsen


I can’t really afford to buy all of these books, so how would you rank them? Prod. Design & Development is a little too expensive for me, so I guess I could eliminate that one unless it’s really good.

You can get it used and cheaper here. 3rd edition which some reviewers said was very similar.

Product Design and Development

I haven’t read any of these yet though so I cannot say for sure which is best.
