>with CyanogenMod / LineageOS most of the good part go to hell, camera goes to hell, performance goes

All that goes to hell because Google prevents almost all first party support for LinageOS (or any other forks), which is why Google gets fined now. In a theoretical world where Google didn't do the things they are fined for, LineageOS might work much better on a wider range of hardware and thus have much more mainstream appeal.
