We used to use Schuko plugs here in Ireland, but switched to type G plugs for convenience and trade reasons back in the '60s. I think my grandparents' house still had some Schuko sockets about the place.

Personally, I'm not too bothered either way. I don't find either any more or less annoying as they're both pretty bulky, unless you're using Europlugs, which lack most of the benefits of Schuko plugs.

Still nothing compares in its awfulness to North American plugs. Aussie plugs are similar, but they had the good sense to tilt the prongs at an angle to give the plug better mechanical stability.

I consider Schuko plugs to fall somewhere between the british and the swiss plug. It certainly is a little too big for what it does, and also hard to unplug. That 16A rating is nice, though.

Schuko plugs are a pain in the ass, because more often then not they require brute force to unplug them (or even just plug them in). Also doesn't help the lifespan of powerstrips.

Being able to plug them in ungrounded Euro sockets is handy, but also makes them less safe.
