Grand China = HU, but mostly newer planes, including some spiffy 330s on the PEK-SEA route. While I always loathed HU, I've heard positive things recently.
I've only tried China United once (TAO-NAY when all of the flights to PEK were sold out). The service was bear bones, but my flight was on time and I enjoyed getting a chance to check out NAY.
