Honestly, as far as mains connectors go, I'm a huge fan of Schuko for two very big reasons:
There's no polarization, so you get away from that faux-safety reasoning behind "well, neutral should never be hooked up to a switch" nonsense with non-fixed equipment. This extends too to equipment with faulty designs, like toasters lacking double-pole switches. It should really go without saying that you should always unplug the device from the wall if you intend to service it.
In addition, Schuko separates the electrical connection from the mechanical connection. This has the obvious benefit that a failure in either won't become a safety concern. Readers from the US will likely understand why this is huge in the context of things like wall warts. (;
