You couldn't pay me to go back to using anything made by Apple or Google. I use a GrapheneOS Pixel and my self-hosted "cloud" with Nextcloud, HomeAssitant, and my own email server and the control and performance are unrivaled by any of the Big Tech crapware. I could start self-hosting an AI chatbot I suppose, but these do not seem to have reached the point of enshiffication yet as relatively new services.
It may be a bit pedantic but Pixel is made by Google. I know you de-Googlefied it by using Graphene but it's still running on Google hardware. I wonder if there are any viable alternatives though.
For the future, Graphene OS devs have stated publicly that they're working with an unnamed hardware vendor to develop a phone that will meet their list of hardware requirements. Currently only the Pixel line does. From what I understand, a few Samsung phones come close, but don't support bootloader re-locking... When you unlock Samsung bootloaders it burns out a fuse on the board which in turn completely disables Knox, their architecture for a trusted execution environment.
