Access to professors outside of class was also difficult. Where I was at in Germany, the professors would have about 4 hours per week scheduled where they were available for help or questions. At the end of each open-hours block they would go out into the hall and tell the 5-10 people waiting in line to see them that they would have to come back in a couple days. Compare this to the university I was at in the US where professors would practically beg students to come talk to them about homework assignments, lectures, etc.
I also had much greater autonomy in the US when it came to lab work (and course selection as well). They trusted us to use the equipment. As an undergrad in the US we were shown how to use an SEM and then left alone with it to play around with it and try different options, scan different objects, etc. For the SEM lab I had as a graduate student in France we watched a technician use the machine and tell us about what you can do with it and that was it. I felt like we were being treated like little kids. There weren't even any machine shops, 3d printers, soldering irons, etc. available for students to use.
In the experience that I had, the US university had much higher quality facilities than the ones I was at in Europe (I'm not talking about the lecture quality here). Certainly, one could argue that the increased cost isn't worth the increased quality, but I did notice a big difference between those four schools.
