Personally I don't think so. There are various thoughts out there about those configurations with a mini cabin as to whether they get better service - they don't - and things like closeness or otherwise to galleys and WC, more for the quieter aircraft such as the 350 and 787-10. I think there can be a bit more vibration on those units attached to the bulkheads but on a 777 there's plenty of vibration anyway. But the seats are identically made and a lot of the debates we can legitimately have on legacy CW seating - in my opinion - now falls away. It's essentially down to what to do for couples and families, but the seat itself doesn't vary.
