There are many relatively market-friendly nations in the EU, especially in the eastern half, but the EU is mostly an extension of the French model and without the British, it really started leaning heavily into the protectionist bureaucratic model. The UK acted as a brake of sorts on those tendencies and its influence is sorely missed, at least by people like me. (Certainly the bureaucrats rejoice.)
* The privatisation of UK railways has been an unmitigated disaster
* The privatisation and selling off of various UK heavy industries (like steel, automobiles, trains, aeroplanes, shipbuilding) has been somewhat of a disaster with the majority of it closing, and the rest being foreign owned. Where the UK were a leader in many areas, they no longer are, with a drastic impact on the people who used to work there. As a counterpoint, France has managed to maintain shipbuilding, airplane, train construction at a pretty good level.
* Where the UK is "better" is financial services - IMO in part due to the English language, in part due to money laundering with the help of the various crown tax havens; and the startup scene - again the English language surely helped, but so did less rigorous labour laws (and that has been slightly relaxed in France).
Anything else come to mind?
"You know what they say about the average Common Market official. He has the organising ability of the Italians, the flexibility of the Germans, and the modesty of the French. And that's topped up by the imagination of the Belgians, the generosity of the Dutch and the intelligence of the Irish."
True. I still think Thierry Breton does a really good job, though, despite being French. Sylvie Goulard would have been a disaster -- she couldn't even speak English!

(The wiki page lies and says she speaks English -- no, she really doesn't. Her German is pretty good, though.)
I think a modest proposal for curb stomping the bad French influence in the EU is to have all EU civil servants retake their entrance exams in another language if they originally took it in French. We should also form an alliance to automatically reject Commissioner candidates who 1) don't speak English and 2) speak French at the confirmation hearings in the European Parliament.
