GrapheneOS leaks less data to Google by default and otherwise than /e/OS and is also a privacy-focused project. I believe places like https://www.kuketz-blog.de/ and https://eylenburg.github.io/android_comparison.htm will attest to that.

App compatibility should also be better with sanboxed-play-services compared to microG since almost all apps/features that don't require meeting certification requirements (e.g. Google Pay and certain banking apps) or privileged integration (Android Auto) should work just like on another Android family OS. Something you might run into is the hardened memory allocator exposing memory corruption issues in apps whereyou might not see the same crashing elsewhere.
