I like a combination - flavor, th and vapor. I like the vapor because it shows me how well my gear is working, seems to help "feeling" the vapor when I blow it out, and obviously shows me where to aim my nose to catch some escaped vapor on the inhale.
As for ecig test videos etc, if a particular tester uses the same pg/vg juice for each test then the visible vapor shows how big a hit you get off a particular ecig.
Bottom line though - you do care about vapor production. You just don't care how visible or persistent the vapor is. If an ecig does not have good vapor production because it's too weak or has a crappy atomizer or bad airflow, you probably won't get good flavor or a good hit.
