I nominate the Swiss plug. It's a compact grounded three round pin plug (only slightly wider than a Europlug), fits in a recessed outlet and the ground pin on the plug is offsett by a few millimeters.
The Swiss grounded sockets also accept two-pin Europlugs.
The Chilean 3-in-line plug that you cite is the standard Italian plug. It comes in 10- and 16-amp versions (distinguishable by the pin diameter and spacing).
My problem with small plugs is that people with arthritic hands will not find it easy to pull such plugs out of a socket. There's one British company that I know of that makes plugs with a pull-ring on the cover (sort of like the handle on a tea-cup).
Also having the flex enter the plug straight on is sometimes good in case of a severe emergency (such as accidental electrocution, mangling, etc.) where you can yank that plug out from across the room (without damaging the more expensive wall socket).
Of course this is potentially damaging to the plug (prongs can break and the cable will develop internal breaks).
