just got back from the trip. I'd say unless you want to the advantage of not disturbing your partner when getting up, the "regular" seats are a bit more comfortable. You can "stretch out" easier and farther under the seat in front of you vs the bulkhead. Me being only 5'6", I do wish they had leg rests on them, but the lack of an entertainment box under the seats were definitely very nice.
They also seem to only have one set of restrooms for Y, so all Y share the 4 restrooms and can cause a buildup after meal times.
