Just flew the following and this is my ranking:
RJ 787 AMM-TLV very old cabin but extremely spacious seats almost lie flat
QR A350-900 Tighter seats but lie flat seats not too much privacy which sucks
QR 787-8 DOH-CRK Also an issue with the privacy factor and very similiar to the A350-900 (I did get to sleep for 6 hours)
OZ A330-300 ICN-IST 2-2-2 configuration which sucks, but I had no seat mates so not an issue. Seats are angle flat and very bad for sleep.
TK 777-300 IST-TLV Never seen such a big space/seat in all my Business Class travels, I mean just wow!! However it is a 2-3-2 configuration good service and the meal was edible (brand from Turkey) seat is almost lay flat.
