Accessing shared data

[beard7]

I'm using the HandleInertiaRequests middleware to made some data available in every request, as described in the documentation.

I'm also retrieving the data in compoinents using the method described in the docs: import { usePage } from '@inertiajs/vue3'

That's all fine and working as expected, but the question is what's the advantage to accessing the shared data via usePage rather than defineProps which also works? Is there any reason whjy I shouldn't accesses the shared data via defineProps?
