The socket in CEE also protect the plug from being hit laterally and damaging either the socket or the plug. In Spain, before the adoption of CEE 7/3 we had europlugs without plug pocket, and I remember half the sockets of the house wiggling on the casing due to lateral hits, and plugs coming out of the socket easily. With CEE 7/3 you have to pull, they feel really sturdy, specially compared with NEMA. I don't have much experience with UK sockets, but I bet they are not as secured (not electrically but as in this-plug-isnt-going-anywhere) as the CEE 7/3.

Not a fan of the protection through a sleeve, as it encourages meddling with the socket with a screwer to use unearthed plugs.

That said, I would like Shukos with fuses, and Shuko plugs unable to plug in unearthed sockets.
