Virgin's A340-600s are the most comfortable aircraft I have been on (so far - I am yet to fly the A380 which I presume will be more comfortable). The 340s are almost silent when compared with the 747 and the noisier 777s. I flew a Continental 777 a few weeks ago, and the engine noise was so loud it drowned out the safety video. Also, I have never found a problem with the seating on Virgin, though I guess it's each to his own. I have never had the privilege (?) to fly in any higher class than economy, so from my experiences, Virgin economy is the way to go!
