its VX or HD. they are just two different styles of how some one would want to film. For example if shooting in film is obsolete then why do they still make film? its just the style that the person wants. HD is more crystal clear, but if it were so much more advanced than a VX then why does this 2013 micro phone that comes stock sound like complete shit compared to a VX micro phone that was made in the late 90's? hahah. Its preference, VX videos have that classic aesthetic we all love to see if you grew up with those videos, and HD just is some new thing that is taking over. PReference is the key word, not better nor worse.
