The piece table is an amazing editor data structure. Reasonably simple to grasp conceptually, memory efficient for large files, good cache-locality, allow easy undo/redo, original file can be read-only, etc.
Newer editors seem to prefer Rope though.

Is there an overview of which editor uses which data structures? I am particularly interested in GNU Emacs, vi(m), Sublime and other popular text editors among Hackers.

Sadly I think plain old Visual Studio isn't getting much love these days.
At least Rider exist, so if they fall too far behind that will just keep growing in market share.

I was surprised they didn’t go with a Rope, too, but I haven’t evaluated one compared to a piece table

I’m surprised they got away with an ordered Array as long as they did. It’s almost prima facia poorly performing.
