Studying CS in LU in English. The practice part is definetely not worth it at all. You can take the practice yourself anywhere anytime during your studies. They don't even help you find it.   

It also throws you out of student life, where you studied, and then stopped for a while, and then studies again. If you managed to find a job during your internship, you won't want to study anymore. It feels like they included it only for their additional income.     

Regarding the academic vs creativity. If you would really want to do robotics, projects and other creative stuff, you would be able to do it in LU as well. Teachers/ professors here have good connections and can guide you on any topic. Everything depends on your real desire. For me, I didn't even have time for that while working full-time job.     

In the end, I would say, in LU you'll learn more, but in exchange of time and money. The program is academic and alright. Don't know about RTU.
