Are you saying an AR-15 can’t take out an attack helicopter at 2000m??

They are very different.

GrapheneOS’ whole thing is security and privacy. It’s big on sandboxing apps and browser sessions. Google Play and most Android features are opt-in (Google Play Services are also sandboxed). Just check their features.

LineageOS doesn’t have most of the above. It’s mostly just a regular barebones Android distribution without all the vendor bloat, and a great alternative if you just want more control and less BS (if you’ve used a Samsung device you will know what I mean - absolutely horrible distribution imo).
