I recently got a Google Pixel as well and immediately switched to it.

I used to run LineageOS on Fairphone before, the only difference I felt is the bootloader locking.

As for comparison between the base OS, well, way less bloat. Its so much less bloat that its quite refreshing to see your phone screen with so little apps on a new install lol.

Only thing that don't work is Macdonald's app for me, but I guess that's 1 more fast food I am cutting down on.
