Pros:

• not as big as the UK plug
• not an American plug
• those power cords that stick out at a diagonal parallel to the wall

Cons:

• no inbuilt fuses
• no inbuilt guard on the socket
• every plug and socket feels cheap.
• thin shitty pins that bend easily
• shitty sockets that break when shitty bent pins get plugged into them.
• used by a handful of people with tight regulations … and China. Good luck getting decent affordable, certified, smarthome sockets.
• that cunt who invented the vertically oriented twin socket wall unit. What a fuckhead.
• those power cords that stick out perpendicular to the wall.
