A big factor for successfully learning while studying is having genuine interest for a certain topic. This will help keeping your motivation (and probably your grades) up, but also later make a good impression on potential employers. I think most IT-related topics have a high enough demand that you'll be able to find a decent job with proper education and motivation, so I'd suggest to go for whatever thrills you most. If you find out it's not your thing, switching subject is generally no problem within the first year or so.
