Trial of the Yellowjacket is the first one that came to mind for me. Pretty iconic in the history of Pym.

I'll second this. Avengers Academy is pretty great overall, and there's a segment during Fear Itself when Hank's trying to defend the kids from Worthy Titania and Creel that's awesome.

It's a Hank-As-Teacher arc overall, and while I needed reminding of it, I do remember liking it.

This is very true. Avengers Academy was a great showing for Hank.

Mighty Avengers #21-36 (2009 - 2010)

This run was written by Dan Slott and had Hank leading a team of Avengers. It was full of nutty, outlandish ideas.

- It cast Hank as the mad scientist that works for the goodguys.
- Hank adopts the superhero name of a hero who passed on, one he considered the greatest hero he knew - the Wasp.
- Pym-Space!
- Hank makes an extremely unexpected invitation for Avengers membership.
- We all know there is a Sorcerer Supreme. Is there such a thing as a Scientist Supreme?

I loved this wacky riff on Hank. I have continued to be sad that later writers ignored it in favor of making him a punching bag/pawn of Ultron/subject of derision. The Mighty Avengers riff on him gave him a weird edge that allowed him to be a flawed man but still heroic.

Ant-Man (2022)

This mini-series wasn't just a Hank thing, but featured 4 different Ant-Man characters, but did include him and his legacy.

Seconded on Mighty! I know it may be hard to tell these days, but once upon a time, in days of yore, Dan Slott wrote very good comics. Between this book and She-Hulk, he demonstrated a particularly strong capability for balancing all of the necessary elements for a great comic - he understood the characters, he understood the lore, he came up with fun and creative new ways to explore that lore without resorting to replaying the greatest hits of the past or going so far left-field as to blatantly telegraph any cynical controversy-courting that feels all too prevalent in comics.

A good "What If" story with Pym is "What If The Avengers Had Never Been?" (Vol 1 / issue #3).
Hank (as well as Wasp & Rick Jones) wears Iron-Man-type armor in that story.
