I can say the same. Been using LineageOS and GrapheneOS for most of my life. Some things are not super convenient (I generally dont install non-free-software applications and don't have Google Play services enabled), but the rest of the experience is great. No crashes, no bugs, no unexpected behavior. Currently I'm using the Pixel 9 Pro XL.
I can also recommend Gadgetbridge for BLE smartwatch integration.
