On the fun side, you could use both bits in the same worktree, to narrow your worktree and have some assume-unchanged files.

Another difference is that with assume-unchanged bit, you make a promise to Git that those assume-unchanged files are "good", Git does not have to care for them. If somehow you violate the promise, Git can harm your files on worktree.
