Agree PEY isn't the best effort CX can provide, but for me however it's almost a necessity. My trips are always longhaul (JFK/EWR-HKG), and sitting in regular Y for 13+ hours is one of the most painful and torturous experiences for me. It's impossible for me to get comfortable in Y, not that it's meant to be a comfortable experience. But while for most people the Y seats are acceptable to get the journey done, it's an extremely painful experience for me and i can never sleep longer than 30 minutes at a time.
Relative to Y, PEY has been a godsend for me.
