That's the thing, though: McDonald's is well structured, easy to use, and consistent - unlike French. And, incidentally, a high quality tool isn't necessarily easy to use - like French.

In fact, I'd argue English fits your three criteria: as it's effectively a pidgin at least once over, it lost damn near all grammatical structures (rendering it simple) and therefore depends on rigid (consistent) word ordering (structure).

McDonalds is the worlds best resturant with that kind of logic.

It is. It's the best at not being shit. You don't expect a gourmet meal, but you get very standardised food no matter where on the planet you are.

Even Michelin star restaurant give you the shits more often than plain old MickeyD's which never fails to have the same mediocre quality.

Just like broken English.

Finnish can do a billion things English can't but English has hundreds of thousands of words, nearing a million if you count obsolete terms, whereas Finnish has barely 100 000 even when you do count even obsolete terms.

So just like with McD, it's the usecase which matters. "Best" is such a subjective term if you don't define it.
