I was forced to fly the dark side (SAS) in Plus for financial reasons beyond my choosing and I felt it less appealing than normal Y on AY as a Plat. On all flights (4) no middle seat empty, and not enough place to put your overhead luggage and the flight attendants seemed grumpy and the service was felt very rushed (of course this is the problem on quite short flights with 8+ rows of plus section etc...)

In my opinion AY Y as Plat beats hands on even their "premium" product. Yes, you get a snack and drinks but that's it. Only talking about the hard product here, of course understand that the "thing" for Plus is mostly the flexibility of tickets etc.
