Other than what I said in the other reply:

I live in the USA so getting one would be problematic but I hear perhaps not entirely impossible for me.

Looks like it has a US release? If you’re unsure or getting a European version, double-check it’s compatible with American wireless network frequencies &c. Specific operators might also have their own shenanigans.

Do you know how it compares to e.g. Fairphone?

Nope, never tried Fairphone.
