So recently my moto G60 reached the end of life with respect to security updates. That was the reason I was using to prevent myself from switching to a custom rom(actual reason is laziness). This phone has rom support for pixel experience and lineage OS. So my questions are if pixel experience has any privacy advantages when compared to the stock rom the phone ships with¿? Also if I flash GApps along with lineage OS will all the privacy advantages I get with lineage disappear¿? I might need Google play services for some banking applications.
It depends on your threat model. If you simply want fewer targeted ads, there is a benefit. If you are a journalist under a dictatorship, there is little to no benefit.
