I have been using e/OS but moved away when an upgrade to the next version required to manually wipe the device. I could cope with the little inconveniences of a degoogled phone, but wiping the device myself following a unclear procedure was too much for me. My phone is not a hacking subject. It's a tool. Still, it worked reasonably well and I would have upgraded and kept using it if the upgrade had been easier.

I am on e/OS since 2021 with a FP3 and, for what is worth, I never had to reinstall, wipe or anything. My phone just had it's 5th birthday and it has been a single continuous set of updates.

I know the versions differ by model, so perhaps your model was not as well supported.
