“Clean Code” or “Clean Agile” (both by Uncle Bob)

I was looking to read through an Uncle Bob book but wasn't sure which one I should start with. *Clean Agile: Back to Basics* (2019) is his most recent publication. I was wondering where it placed in the ranking of his published material and if it was worth picking up before reading his *Clean Code: A Handbook of Agile Software Craftsmanship* (2009).
