Yes, the 789-9 and 789-10 are decent - basically the 777-300 without the door. It's the 787-8 that's to be avoided (at least for me). It has the original F with folding (and very slow) IFE and some planes have no wifi, from what I remember, meaning it's a long flight without an internet access.

However, the space is much bigger than business. The Club Suite feels cramped in comparison.
