Apples and oranges. They are both excellent series and well worth anyone's time. I don't see why they would have to compete.
That's where I fall. B5 is my favorite of all time, but make no mistake I still thoroughly LOVE "Farscape". They are completely different from each other, going so far as to being produced in different countries. Different kinds stories, different techniques, different everything. And that's a large part of why I do thoroughly enjoy each show
