Asiana has definitely fallen behind. I would still prefer to fly Asiana over UA on that route. I also much prefer Qatar's Q Suite, I'm not going to fly through DOH to get between ICN and SFO. The Business Smartium seats on the A350/A380 are not the greatest but they're not bad. I do draw the line on flying on Asiana's A330 in business on any long haul flight.
