I’d rate US ATC services as similar to many 3rd world country ATC services. Their use of non-standard RT, lack of empathy with non-english speaking airline crew, ridiculously fast speaking and unnecessary visual approaches for long haul airliners causes unnecessary extra RT, go-arounds and incidents.
You obviously haven’t been to LHR. Now, that airport definitely has the best ATC services in the world. And guess what, it’s limited on real estate, maxed out capacity wise and doesn’t need the use of visual approaches to achieve that capacity.
With the odd notable exception, I sadly have to agree with that description. Most of them need to be seconded to LHR ATC for 6 months to obtain an understanding of how professionals do that job (and to learn a few manners).
