If you have the time and patience to do a nice job murdering chips I'd recommend doing it that way over milling (unless it's a hotstamp of course)
I always see small pieces of inlay left behind on milled chips and they just never look as good as a proper inlay replacement. Plus you quite often get rough edges, from what I've seen.
Here is a closeup of a chip with a gear laminated label. This chip was a hotstamp chip that has been milled
