Most people will think that an open degree is worse than a named degree because the perception is, rightly or wrongly, that you will have sacrificed depth for breadth and, in doing so, not learned the same skills as somebody else. I don't necessarily think this is accurate but it is how some people feel. This said, depending on what you plan to do with the degree it may not matter very much at all.
It is also worth noting that many people with an open degree, from the OU for example, still put a named degree on their CV which best matches the modules they've taken. I wouldn't advise this because, as a recruiter, when I checked their certificates I considered them somewhat dishonest and this isn't a risk you need to take when it's not necessary.
What are your career aspirations? Will it matter in the country you live in?
