This - plus the convenience of not having to have mounts on multiple bikes. The phone app will work through data or WiFi which is a nice feature if you have a teenage daughter who is always on the computer.
I don't know about the phone accuracy with different phones or different parts of the country but mine is fine. And I deny that barometric altimetry is significantly more precise than whatever the phone app uses - they both have some variability and are more or less accurate in different situations.
There are some nice advantages to the Garmin devices, but I don't think Strava functionality is one of them.
