I can't compete with an account of service in any of the various first class cabins. I've only travelled in first class once, from Penang to Singapore (via KL) on MAS. (AA first class on a J class QF ticket doesn't count.) If I planned to travel once every two or so years I might consider flying first class, but I hope to travel more often.
I value a decent experience in the air, and in the lounge before departure. I flew economy SYD-DFW early this year (in an A380), the service was good and I was complimented for wearing a jacket and tie (why they would do that I have no idea). The person in front of me said that they had requested a vegetarian meal, the cabin staff were unaware but arranged for the first class chef to prepare a vegetarian meal for the passenger.
On my return flight I upgraded to premium economy. First class it ain't, but the leg room and the service was good. More recently I flew across Australia in business class (flat bed seats, but it was a daylight flight so who cares), and taking into account the business class lounge, I was sufficiently pampered.
I understand that competing first class cabins are interesting, but for me competing steps above economy are enough.
