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.
