Type J is superior in every aspect.
-compact, you can fit 3 plugs into an outlet while Type F only fits one for example.
-robust.
-cannot reverse polarity.
-no fuse required as the law requires proper fuses in every electric installation with law enforced periodical checks.
-round pins that cannot puncture your skin if you step on them. It’s hard to face the pins upwards anyway.

Type-N is even better, it’s essentially a Type-J with some improvements
Compact in one dimension, but it is very long.
This makes it awkward in tight spaces compared to something like a UK plug.
You have this and variants of it, with the plug being recessed you could probably have it take up less space in all dimensions over the UK plug
