I don't see what BSG has to do with Voyager other than they're both spaceships in different universes.
it's funny, I've heard a lot of people compare the two shows. Maybe because they're both about ships trying to reach earth. But really, how can you compare the shows? Their core principles are so different. BSG was basically the worst case scenario of the "future", no advanced technology, still had disease, poverty, petty bickering, and the bad guys won and destroyed everyone
Trek has always been the best case scenario of the future. Advanced technology, no disease that can't be easily cured, no starvation, nobody is poor, even the mentality of people is completely different.
that's why voyager always looked nice
