As this will move over to the DL Forum, I'll still weigh in. I was in 5D recently. It was nice because not too close to the front galley, and the pilot rest seats were behind me. I wouldn't choose a window seat because of the person next to you, but that's just me. Row 6 does fully recline. If you're traveling as a couple, then I would go with A/B, but as a single, I like the middle seats.
