One extra point (in general I agree with Alex Sergeev). I studied both in Russia and Israel (Technion – Israel analog of MIT – AFAIK Israel high education system is much closer to USA, many professors worked at some time in their careers in leading USA universities, many students do their docs / postdocs in USA etc). While textbooks generally speaking were better and “easier”, and courses materials were presented slower in Israel, teaching capabilities of professors and teaching assistants were much better in Russia.
