How to assess the quality of a degree?
Many universities will publish statistics on how many of their graduates are employed or in further education within X months after graduating. If you're only concerned about getting a job, then that's probably your best source of information.

That said, in the end it depends on you. People get jobs with crappy degrees and fail to get jobs with really good degrees. Whether you'll be able to get a job in your chosen field will depend on what exactly you do for your degree.

A good opportunity for improving your chances of getting a job after you graduate is to do an internship while you're at university. Many universities have job centres or similar that can help you with that.
