I agree with all of this, and I want to add that it's truly cross platform. Their web app is the same experience as their native app (this suggests electron but I'm not an electron hater and the native app is not a resource hog). It also has native builds across platforms, including mobile which is also well done.

There are other good note taking apps out there and there, and there are other note taking apps out there that solve the device problem I struggle so much with. But notion is the best note taking app with the best cross device/platform support I've come across.
