We did it last year prior to them jacking up the price. It went from around 150 euro to 600! It's business, but it's pretty mediocre other than the seat itself. The food is meh, and being in a 321 means either you are tripping over someone to get out to use the bathroom or you are the one getting tripped over. French airlines also like to keep the cabin uncomfortably hot, which sucks in the winter when you tend to wear heavier clothes. And then there is the worst part: EWR. Glad we did it, it was nice to sleep on the way over although it wasn't great sleep and to get to experience it for $150 each. Won't do it again, especially for the new price. Not worth $700pp at all.
