I'm intrigued to see both films but Eternals more because it looks the most ambitious and has the most potential from its source material. Shang-chi looks to have the best action in a marvel movie but eternals could have the best story.

Shang-Chi looks like it will be a fun summer flick, but The Eternals feels much more profound and will surely lead to a very interesting addition to the overall MCU storyline.

It looks more visually, and tonally, interesting and unique.

I think I’m more excited for Shang Chi, but I’m beyond intrigued by the Eternals because I really have no clue what we’re getting and I can’t wait to see what Chloe Zhao brings to the table

I want to get into martial arts movies, and this looks like a good start.

More visually and tonally compelling. Looks less creatively compromised. Better cast. More stylistically distinct from much of the MCU. Based on more interesting source material.
