Welcome to Flyertalk and welcome to the BA forum rfarlz. It's good to see you here and I hope we will continue to benefit from your presence in the future. Welcome on board. Actually I don't think you're the only person to have this view (not least because I am in the same zone) so there are other threads on this topic, but none with the ranking that you have kindly provided.

I would actually place the CW seat a bit higher up your list since I dislike the Cathay seat for various reasons, though I otherwise like the Cathay product. The key to me, as a frequent flyer, is sleep quality, and a 787 and 380 CW seat plus the White bedding remains the best way for me to achieve that, with UD 747 not far behind. Partly is due to being used to the seat so much, partly that I can normally get my preferred seat, partly that I don't need to visit the washroom so often,, but in the case of Cathay and Qatar it truly isn't due to a shortage of trying. So I'm one of those slightly worried that the 350 product won't be as good a sleep product as the current seat. After a set of QR, AA, and CX flights I really look forward to a BA service, since I know it's going to work for me. Sleeping rearwards (and so at the right angle) is one important factor.

But it's not for everyone, there are many here who indeed strongly disagree, but as your list illustrates there are plenty of alternative airline available for those who don't like the CW seat.
