It's worth noting that on the 777 60A or 60K has a window. It's offset back just a little but you can still look out if you like. 45A or K has no window. I vote 60A or 60K on the 777 as the best economy seat in the world. I even still like it better than 85K on the 747 although that one was nice too.
I calculated it up one time and figured I have literally spent several
months worth of my life with my butt sitting in EVA economy seats.
jimbo99's assessment is spot on. As for seatguru.com, I don't believe they have ever seen the inside of an EVA plane.
