The /e/OS version of Fairphone 6 is still almost 50% cheaper, while providing slightly higher IP rating, 3 years longer warranty, schematics for board repair and a guarantee of 8 years of software updates. In addition to that, the phone is built ethically.
Murena phone has a faster GPU (2x) and up to 36% faster CPU, but only 2 years of warranty and 5 years of spare parts. Fairphone still has spare displays on sale for Fairphone 2, which came out a decade ago.
Hiroh phone also has a “sustainability” field in the specs, which is nice and empty
One thing to note is that the ANC shuts down during charging (so does Bluetooth) but you can still use the wired connection.
