I love VX. I just committed by dropping my BA Visa for a VX Visa because I hate flying American and I happen to do almost solely ORD - LAX.
It sucks because barrier to entry in this market is brutal. The product is so much better than the competition though. Hell, I booked an AA F fare on points and specifically went for an afternoon flight so we could get the 767 with the international business class as first and it was still terrible.
