I wish to transfer to a university in Europe, to complete my engineering formation. I thought it might be the opportunity to initiate a discussion on the merits of European technical schools, given how many people here have a STEM background, and have experienced the first-hand.
Which ones do you think are best at teaching? Which provide the best starting point, professionally? Which have the most productive, idealistic mood among the studentship? If you've been to several of schools, how do they compare to each other?
The floor is yours.
With such an open question, I doubt you're going to, for the reasons I wrote above. People are going to either know about zero European technical schools or about one of them, in either case, they can't contribute much of a comparative analysis. If you want to know about studying to be a transportation engineer in Germany, why not find a German train enthusiast forum or something and see if you can ask there?
Also, I don't see why those tell "almost nothing". In the US, going to MIT seems to be a pretty good recipe for training to be a hardcore engineer, both due to the strict curriculum and the fact that you're going to be surrounded by the sort of people who can get in and successfully study at MIT. From the list, ETH Zürich seems like a quite similar school in German-speaking Europe. You're likely to be surrounded with and socialize with very capable and driven people and get taught a lot of engineering for your degree.
Schools are not as drastically different in prestige in Europe as they are in the USA, except maybe in France. Even then, you get surprises. My current school is one of the most powerful and dynamic in the country, and even the world, and generates patents out the wazoo, yet our building is crap, and our students and professors don't seem to give a crap about the learning and teaching; it works more like a research laboratory than a teaching institution. Numbers and rankings couldn't have told me that, and I curse the day I set foot here. I'm trying to get out into some place where my fellow students won't call me a nerd for actually taking an interest.
