Even on non-pixel devices, unless you really want to use the /e/ "ecosystem, there are probably better options like LineageOS for microG iodéOS.
(/e/ used to be heavily based on an outdated version of LineageOS for microG. I'm not sure what the current state is after I settled on second-hand pixel with graphene)
iodé is available for my device as well, but it looked fairly similar to /e/OS to me (and the latter has an official partnership with my phone's manufacturer). What makes it a better option - should I switch?
