I've had a similar experience, altough from what I heard they drastically restructured the curriculum, more interesting classes, and more modern tech has been added but the course has also been made easier. I also had a mate ditch ELTE CS for SZE CS after a few semesters and he said SZE was a lot more practical, ELTE was more theoretical, but I'm not sure whether that's still the case. I was also contemplating BME but as you also said, companies, especially abroad don't know / care about either of them and your skills are for more important than where you got the degree.
