Pretty much would agree with all of this!
Shadowland was terrible and I felt Waid's take was especially needed given where Matt was following Shadowland. And while people criticize it for not being dark enough I thought Waid did have some darker elements like giving Foggy cancer or revealing the truth of why Maggie left (which was an amazing arc). Soule's run was solid for the most part and loving Zdarsky has done so far!
As for where to start, agreed the Miller stuff is a good place to start; otherwise, you can start with Kevin Smith's Guardian Devil (not the biggest fan of it honestly though it it is a good starting point). I would also add that I think Parts of Hole, Daredevil: Yellow and Daredevil: Redemption (to me the most underrated Daredevil story) are all worth reading as well and were all released around the Smith/Bendis/Brubaker time period.
