I just got off the flight yesterday, and yes, exec economy is great value for money. It's definitely not J, but I really could sleep, the service really is great, and the AVOD will keep you busy. There are also powerpoints for your laptop, so don't forget to bring your power chord (as I did) on the plane with you. All in all, I'd still choose J, but given a choice between 18 hours in this seat and 12 hours in regular Y, I'd choose this any day. I even had an empty seat next to me, so it was really quite pleasant for such a long trip......
