if you ever get to fly the current UA J product you'll beg for your DroopBed on QF i can assure you
look this is like everything... all things decline over time - due to cost cutting and product changes, but also ddue to one's exposure to the product, flights etc. There's probably some rich so-and-so who is bored with EY's Residence or can find fault with it
And dare I say with reference to the OP, who is flying on the boss' dime, the most important factor should be ability to be productive if that is required on the flight (or to be able to sleep). Now this is where the noise issue (from children, crew, or whoever) comes in.. you can't pick your seatmates, but you can pack some good NR/NC headphones and find strategies to make the flight more acceptable.
I also agree with what others have said.. a good crew can make all the difference - on ANY airline (yes, even UA!)
my 2 cents
