They make a lot of high quality shows in my opinion, and have made a lot of great ones in the past. Max is a better service than Netflix in my opinion.
HBO make shows that feel closer to the "human condition" than most other companies.
Max has the following great shows:
Game of Thrones
House of the Dragon
The Sopranos
Oz
What We Do In The Shadows
The Wire
Silicon Valley
Rick and Morty
True Detective Season 1
Rome

HBO has always had a pretty nice spread. It's not the newest it's not the hottest, But there's usually something on there that I want to watch, coming from the let's just log in and see what there is to watch scenario. I hopped onto Max when they brought all the old cartoons over, I started ripping and stripping for all I was worth because a lot of that stuff was not readily available at the time.
Then they had their big shutdown and they lost a lot of that content and I walked away right then.
You're still good for streaming reruns of decent rewatchable movies though I'd say more so than Netflix.
