Never flown VS so can't comment but BA WT+ is IMO an excellent product for the money, once you have done a trip you'll never want to fly WT again and will always be able to justify the extra cost for WT+ to yourself. If you go the extra mile for full business class on BA then make sure someone else is paying 'cause if it's your own money the real differences between WT+ and Business are not enough for the extra dosh. Fly BA WT+ and keep the extra in your pocket everytime.
