Hey Epic, from your list i would recommend either 8 or 14 with a slight lean towards 14. The First half of 8 is Fantastic, But the second is a Chore to Watch. you might get bored. 14 is much more consistent.
15 Is good for the first three weeks. In fact i think it has the best first three weeks of all the C5 Series. it goes downhill after that though.
