For one thing if you're snapshotting your subvolumes for backup purposes then it will ignore nested subvolumes. Eg you dont want to preserve snapshots of huge installed game directories, cache directories, logs or docker / podman images, usually. Saves a lot of space.

Also you can tune copy on write on a subvolume, which is great for some use cases for performance.
