A local playlist is a saved snapshot; a remote URL can let the player fetch an updated list. Neither is automatically better for every household. The useful distinction is whether you need source updates, a stable personal copy, or a controlled test that will not change while you investigate an issue.
Understand the update trade-off
A local file will not automatically receive new entries or corrected addresses unless you replace it. A remote list can change on refresh, which is convenient for maintenance but can overwrite edits made to a downloaded copy.
Protect both forms as account data
A saved playlist can contain credentials inside every stream URL. A remote link can contain them once in its query. Treat both as private, including backups, email attachments and shared folders. File format does not reduce the sensitivity.
Use a snapshot for comparison
A dated local copy can help show that a channel was renamed or a group changed. Keep only what you need, with restricted access. Do not keep indefinite archives of live credentials just to document cosmetic differences.

An example to work through
A local list saved on Monday may keep an obsolete channel address after the remote source is corrected on Tuesday. Refreshing the local file requires replacing the snapshot.
