I like ANA PE. The food was excellent and you can also request for the business class dessert for your snack. On one flight, the flight attendants served PE a second dessert from the business class. When I started flying NH, I had no status so the lounge access was great. A shower after a flight is always a delight.
I have not tried Delta PE but have done their comfort plus many times. The latter is just not much different from coach.
