I have both an inReach and an iPhone 14. Haven't made a decision yet myself if I will keep it. Some pros for the inReach:

1. It's nice to have a backup. 2. The battery life on the inReach is upwards of a month and it's more rugged. 3. You can throw it in your pack, forget about it, and somehow it stills gets a signal. 3. Garmin has a dedicated communications center (IERCC) that has tons of experience coordinating with first responders. They will keep your emergency contacts updated about your rescue. Apple's system is less proven.
