How about both options and each one chooses the one they prefer?
Remember to only send the NIP-95 to those who support it.

Nice. We can easily add an extra field in the user metadata and include the nostr:event with the nip95 content. Clients that support it wouldn't need to load the http content..
It could be confusing though to change your profile in a client that doesn't support nip95 and have the url link point to a different image than the nostr:event field.
NIP-95 will not be supported much. for profile picture may not be a good option. Because there will be customers who will not identify the photo.
