To summarize, On a rating system 1-10, I'd give the EY Apartment a 8.5, the same rating I'd give for SQ F and EK F.
The reason, Due to the fact that the seat barley reclines, EY could've easily pulled off a home run, but that one flaw kills it.
I've already flown 8 of the best F cabins, which I'll list in order of rating IMHO
(1) 1. EY F Cons: Seat doesn't recline much, Lavatory is small (relative to EK F)
(1) 2. SQ F Cons: No lounge area, No shower
(1) 3. EK F Cons: Suite is narrow, small, relative to SQ and EY
(2) 4. CX F Cons: Not the newest aircraft, No shower (the A380/787 flight experience due to the quietness of the engines really makes a big difference)
(3) 5. Lh 744 F
(4) 6: BA F
(4) 7: AA F (A321)
(4) 8: UA F
I'd put EK, EY, SQ on a tie for #1 and BA, UA, AA at #4
I only wrote about the cons of the top 4 to bring out the differences.
