I am looking to book a personal trip to Asia this year and while I prefer ANA and Asiana for J, I am tempted by the Chinese airlines super-cheap business class.

I've searched and read the horror stories. Anyone have any recent experience? The YouTube reviews seem decent. I've read about the crew smoking, the bad food, the lack of customer service, etc.

Is there any one that's better than the other? I am open to joy-riding any of them. (China Eastern, China Southern, Air China.)

Apologies in advance if this is in the wrong forum, still learning the ropes.
