"One thing HBO does that Netflix doesn't do is make sure that the opening theme is awesome."

That is such an astute observation. It is obviously a winning and deliberate HBO gameplan, as those titles must cost a FORTUNE.

Both Game of Thrones and Westworld title themes are not only brilliantly catchy compositions, but the images sum up concisely and imaginatively everything those series are about, and they last a long time. The overall effect is escalated anticipation, as well as a sense of occasion.

I am with you on "Game of Thrones," though I adore "Stranger Things" as well, and since GOT is ending in 6 episodes, you gotta look elsewhere for exciting ongoing narratives.
