The contrast is interesting. When I started using Global Entry ten years ago, I missed getting the US stamp upon returning - different points of entry (LAX, ORD, JFK, etc.)
Then when other nations stopped stamping upon entry/departure.

That said, there are still times when the passport gets stamped because I'm doing short hops/day trips back and forth across borders. The daytrip ferry ride from Buenos Aires to Colonia gets a lot of stamps - out of Argentina, into Uruguay, out of Uruguay, into Argentina. It gets filled pretty quickly.
