Some of the Apple integrations are so great. Copy and paste between devices, airdrop, call handling and messaging, the notes app, preview app. PDF handling (my god is the windows default hot garbage in comparison).
Yes, other apps and companies do this, but out the box there are some pretty great options from Apple.
Using my IPad as a second monitor still feels like sorcery. I can have a dual monitor setup wherever I work without cables or fuss.
