Hetzner also tends to have more modern SSDs with the latest nvme. Which can make a massive difference for your DB.

It's less about the modernity of SSDs and more about a fundamental difference: all persistent storage on AWS is actually networked - it's exposed to you as NVME but it's actually on a SAN and all IO requests go over the network.
You can get actual direct-attached SSDs on EC2 (and I'd expect performance to be on-par with Hetzner), but those are ephemeral and you lose them on reboot.
Wow, that's crazy, I was wondering why the numbers I were seeing on AWS were so much worse. I assumed it was the drive modernity. But network makes a lot more sense.
Thanks for the insight!
