Evergreen Deluxe is definitely not comparable to international business class, but also definitively a very good value for money.
8 seats abreast in a 747 (2-4-2), a seat pitch of 38”, personal video.
When taking into account the price (discounted tickets), it is a really good product in my opinion.

The only negative point is the food, very Asian-oriented (but it is difficult to complain, on my Europe to Taipei flights the vast majority of passengers are Asian, the product is not very well know by Europeans).
