I’ve seen the 1982 thing pointed out before, and I don’t think you can find another year with a list like that.

I like The Forever War, it’s certainly a more complete novel than Starship Troopers. The more visceral parts of ST are better though.
They see the enemy numerous times (and it has as much action as Starship Troopers), and the “everyone’s gay now” thing hasn’t aged well and is a big part of the book, but I don’t think you’re remembering that part correctly either. There’s some sort of procedure to change their sexuality, people don’t just “decide to be gay.” It doesn’t make literal sense though, they could just sterilize everyone.
Haldeman denied that it was a deliberate rebuttle to Starship Troopers. It’s certainly influenced by Starship Troopers and parts of it are a defacto rebuttle, but it’s mostly about the world changing while people are off to war, which isn’t something that really engages Starship Troopers at all. My favorite subversion of Starship Troopers is the stuff about how easy it is to accidentally kill yourself trying to use the power armor.
The sequel, Forever Free, is one of the most ridiculously awful things I’ve ever read in my life. I assume you don’t want to read it if you didn’t like the original (or even if you had), but this review summarizes it pretty well (spoilers, if anyone was ever thinking about reading it) https://www.kirkusreviews.com/book-reviews/joe-haldeman/forever-free/

I like the Delaney I’ve read, and have been meaning to reread those books and read some of the others. I’ve never read Stars In My Pocked. I’m not sure I’m ever going to read Dhalgren.

just page-turning, exciting pulp fiction in an Edgar Rice Burroughs/Sax Rohmer vein.

Do you like Edgar Rice Burroughs? I don’t. But for that kind of thing, I do like Robert E. Howard.

I liked More Than Human too. That and Childhood’s End make an interesting pair of 1953 classics.

Eye In the Sky is my favorite 1950s PKD. I haven’t read The Cosmic Puppets, but it is unlikely to be better.
