Contact hours don't actually tell you anything significant
It certainly wont tell you which is the 'better' course, or where you will feel happiest.
Degree study is about self-study, library research etc, not just formalised teaching, and most Soc-sci or Humanities subjects wont have as much face-to-face as STEM subjects. And remember, 'contact hours' can be 'sat in a 400 seater lecture hall for hours' not just classroom teaching. And these 'hours' change as you progress through the course. So, trying to deduce anything meaningful from what a Uni tells you are 'contact hours' is a bit futile really.
