I also just switched from iOS to CalyxOS with a new Google Pixel 6.
Surprisingly, I am very satisfied with the operation and have not had to make any sacrifices.
The only thing that keeps me from leaving the iPhone at home is the Apple Watch and that ClayxOS for the Pixel6 is still beta. If something does not work, I would have a backup with me, but so far there have been no problems at all.
Does anyone of you use a smartwatch with LineageOS or CalyxOS that is recommendable?
