My vote goes to 85A or 85K - these are the bulkhead window seats in the UD. I've done the west coast to NRT route several times last year and liked these seats the best. The main reason is that I'm 6'3" and there's no seat in front of me to hit my feet when it reclines. You may have to step over the footrest of your seat-mate to get out, but at 6'3", this was not a problem for me. The window seats in the UD are nice since you have the bins next to you. They make handy tables too.
