Image

Right - Blown insulation in existing attic provides even coverage completely filling the attic space to a depth that covers the ceiling joists.

Image

Wrong - Batt insulation does not provide complete coverage across the attic floor so ceiling joists are exposed resulting in thermal bridging.
