Truth is the education quality doesn't correlate that strongly with "top" University ranking; at above top X ranked university, or top university in respective country, the quality of education is mostly the same. The difference in the ranking only really reflects the research output/opportunities and networking opportunities.
This becomes so glaringly clear as soon as you start being the interviewing side of the job.
European elites seems to not go to US top universities either; top talent (in intelligence) from upper middle class and above, maybe. But there's more to gain networking in their own countries top universities than abroad. (hence the exchange year system for that)
I think the point of the top level comment here is exactly what you've said and additionally that the networking opportunities are actually what matter for success.
But it is RWTH
I went there because it was supposed to be the best university in my state. But it did not help my career at all
I should have tried to get into a US university
The premise is faulty from the onset. Most ‘top’ European schools are mediocre outside of liberal arts degrees.
