Maybe. In my experience over the last few years of doing a lot of long haul flying in economy, there's not much difference in seat layout between airlines though, it's mostly about the plane you're on. A380s have nice big seats, the rest are pretty similar. The pressurisation and quality of air conditioning on the other hand makes a big difference to my quality of life personally, and that's noticeably worse on 777s.
