Worktrees effectively share the entire state of the repo. Only limitation is that a branch can only be checked out in one repo at a time.

Clones only share the immutable object store

For most practical uses of same repo checking out different branches locally, worktrees are better.

The nice thing about clones is that you can have a backup clone, a wip clone, a review clone where you don't clutter the amount of local branch refs
