Just shows you how much you know about ATC. The holding situation at Heathrow has very little to do with inefficiency of UK ATC.
Does it mean 1/"holding at BIG is perfectly normal, UK ATC is totally inefficient but this is not the most spectacular proof" or 2/"BIG is the most crowded holding in european airspace but UK ATC is nonetheless perfectly efficient" ?
What about the replacement of those 1940s VHF ?
This said, as a user, i find UK ATC comparable to french ATC, both have pros and cons, result is pretty much the same. For real bad ATC try Angola or India
