Yes, Lineage and Graphene are far more usable than people without first hand experience imagine. The vast majority of Android apps just work. Some may display a warning when first launched about custom ROMs being "unsupported" (like Whatsapp), but then just work as expected. A few users also report broken notifications (those that use Google's library to implement them), but it's a minor inconvenience, at least for someone like me who dislikes notifications.

And there are many great apps available on these free Android devices that are simply not available on "official" builds such as NewPipe, because Google obviously doesn't want you to block ads on Youtube.
