It depends a lot on the plane. There is much less recline than on an AA ~60" pitch J-seat. My experience is AA 60" is a much better sleep even if not lie flat. Haven't flown UA J for a while, but seatexpert shows a lot of widebodies still with 38" pitch - in which case sleepability VS PE vs UA J is be comparable from my experience.

VS PE food is not up to much; it's OK, but not what I'd describe as "decent". BA WT+ is another option you might consider. Seat is comparable to the old VS PE, but I hear that the new VS PE seat is way ahead of BA.

One tip - if you go with VS PE, be careful to get a seat without the AVOD box under the seat in front of you.
