Well, obviously "Do Androids dream of electric sheep" simply because the movie left out a little bit too much, which you can catch up on when reading the book. Keyword "Mood Organ".
I also liked "Second variety" which has also been rendered as a audio play IIRC.
And, for the non-sci-fi part, A Scanner Darkly is pretty weird. Has also been rendered as a movie...
100% solid agree. That's what makes a book worthwhile to read.
I saw The Man in the High Castle series when I had time for webseries, and while it was kinda mid, it had some great aspects.
Suggest more if you can. Need not be Sci Fi.
