I don't quite understand how people can prefer VS' herringbone, or any airlines with herringbone for that matter. Effectively you're cocooned by high walls on both sides of the seat and you stare right at the person sitting in front of you at all time. That's why CX rolled it out for a short time, had an avalanche of negative feedback, and switched to the reverse herringbone.

Whereas on BA's CW while the yin-yang layout is past its sell by date, you're cocooned only on one side (except for the middle 2 or 1 seat) and you don't have to see another person once the divider screen is up.
