The UK Type-G plug design is very well thought out. The ground pin is first to make/last to break and it opens a cover on the live terminals when inserted to prevent accidental contact to live components. The power pins are recessed so you can’t accidentally (or intentionally) make contact with life parts of the plug is only partially inserted. The plugs also have internal fuses (although I’m not sure if this is always the case).

The only negative is the plug is physically larger than plugs used in other countries. This makes them take up more space in a bag/backpack. And it’s harder to cram lots of sockets into a small space like a power strip.

The primary danger from British plugs is standing on them, barefoot.

German plugs are almost as safe electrically, and hurt less when trodden upon.
