Harsh but true. It's the same phenomenon as defending the BS 1363 power plug that needed an embedded fuse because their domestic postwar electrical wiring was Not Great -- to save on copper.
Yeah BS 1363 is a really weird British standard to pick on, especially in a discussion about our food standards! Well engineered to actually stay in the socket, sockets have safety shutters as well as the earthing which other standards bizarrely lived without and it's not easily confused with a myriad of similar but incompatible standards. The fuse is a non-issue in practical use, and handy if your circuit is high current and your power cord isn't.
People who prefer plugs that are fun to step on are doing electrical interfaces wrong!
They're all horrid to step on, so that's not really worth discussing.
The US plug (NEMA 1-15P is the 2-prong version, or 5-15P for the most common 3-prong grounded) is actually pretty decent. They stay in sockets pretty well if the sockets aren't bottom-of-the-barrel garbage products which, sadly, many things in the US are in general.
What many people miss when comparing US and EU plugs are that they're actually doing fairly different jobs. The 120V mains in the US is significantly less trouble than the 240V in Europe, so you can get away with a lot less mechanically on the plug. The US NEMA 6-15P plug design (the 240V version of the standard plug) is, accordingly, kind of shit. But at least it's rare enough that receptacles tend to be of decent quality, which mitigates a lot. The locking versions (L5-15R etc) are actually quite good, and should almost always be used when possible and appropriate. They're good to 480V and even a bit beyond -- not just working but actually good -- and you can't say that about most EU plug designs. You guys have those horribly bulky pin-and-sleeve disasters and we get nice NEMA locking plugs for our three-phase.
One of the other things that European plugs have to deal with, and US plugs don't, is that European electricians have no idea how to separate hot and neutral wires and basically wire them up randomly. This has major consequences in a lot of product design and is really really annoying when you're trying to build something safe. (Namely: in the US you're often (but not always) not allowed to fuse neutral wires. That makes sense, for safety reasons. You have to fuse hot... but in Europe you don't know which one is hot, so you have to fuse them both. Which means you just fused neutral. Design conflict!) That shows up in the plugs, too; with no idea where hot is, you have to be more careful and can't use neutral to help you out.
British plugs are worse to step on, not because the pins are any worse to have jammed into your foot but because the design of the plugs means that if you leave one unplugged on the floor there's an excellent chance that it ends up in caltrop configuration with the pins pointing upward, whereas a US-style plug is (I think) more likely to end up with the pins pointing sideways where they're less likely to hurt your foot when you step on the plug.
But in all other respects the British mains plug design is really rather good. It does a good job of making partially-plugged-in plugs still safe, it's nice and robust, it readily stays firmly plugged in, etc.; US plugs are much worse in these respects and I think so are typical continental European ones.
BS 1363 isn't an EU plug though. Doesn't have issues with separation of hot and neutral wires (and does have a fuse for the hot wire built in) and nor is it specified with the idea that electrocution risk is no biggie or that not falling out of walls (a big issue with some Euro plug and socket combinations too) is up to the manufacturer. And having one type of plug for all regular home appliances in the UK and a different one for three phase feels like a more sensible split than the range of 2 and 3 pin options of varying quality and compatibility that CEE7 and NEMA present.
Fair point on BS 1363 not being EU, and about UK electricians not being incompetent (I actually didn't know they were careful unlike the continent -- that's just one of those things that once you have to deal with the insanity that is continental Europe, it doesn't really much matter what else is out there).
But my point about electrocution risk is that 240V is not twice as dangerous as 120V. It's actually much, much worse. And 480V is worse still. We used to say that screwing up 120V will hurt you, 240V will kill you, and 480V will kill you, start your corpse on fire, and blind everyone around you. So the design requirements for all 240V class plugs are much more important.
not falling out of walls ... is up to the manufacturer
This one is a real problem in the US because there is a standard, it is a good standard, parts are made and tested to the standard, and standards-compliant parts work very well. But few people require the damn standard. If you want good receptacles in the US, get stuff that's marked "Federal Specification W-C-596 rated" (aka "Fed Spec"; "Spec Grade" is self-certified to... something... which is... not the same thing... but in practice the manufacturers seem not to abuse that term too much; often lower-volume part numbers seem only to be available as "Spec Grade" presumably due to testing cost). It will perform well.
As a Brit I will tell you that not all of us like this processed shit that passes for bread.
However the plug is actually a really good piece of engineering. There’s so many subtle design features to it that can be genuinely life saving. The only drawback is the often cited problem of stepping on one, to which I say “you shouldn’t be leaving plugs on the floor anyway. And it’s still better that than having kids electrocute themselves or your house burning”
The peak of British engineering was in the 1990s when I briefly lived there, and you could not buy small appliances with a plug attached. You got the bare wire, and you had to buy a separate plug, and connect it yourself at home.
Of course, any rational British person would instantly understand that the best way to ensure safety is to have every single person wiring up every single plug in their house.
Mostly I’m happy about that, but you can’t remove the plug from dead appliances anymore and keep it (along with the 48 other “spares”) now they are all moulded plastic.

But we all do this with our own stanky poop.
The plug ain't too bad actually. (And I grew up with European style plugs.)
Still a vastly better mechanical design than what they make you use in the US: they barely hold in the socket.

US plugs (and similar ones like Japanese and to a lesser extent the Australian ones) are really bad.
European ones mostly stay in the socket. But I guess they ain't quite as cleverly designed as the British ones.

For the US, you really need to be careful to get something that doesn't fall out of the plug.
For the British standard, pretty much any plug you can buy will be fine.

The law changed in 1994 requiring appliances to be sold with the plug attached.
