I was in this configuration a few nights ago, AUH-LHR, in an aisle seat while my companion was in the middle facing back. My experience was very positive, perhaps because I was expecting the worst (as was my companion). I found the seat surprisingly comfortable and I actually had a good, although short, night on it. It wasn't too narrow as business seats often are (AB) and there were no weird lumps or joins (LX), the pillow was not too tiny (KL) and there was decent lumbar support.

The back to front design was no problem when watching IFE and my companion raised the divider when he went to sleep. I liked the way you could move the meal table back and forth so you were never a prisoner in the seat, especially during meal times. I used the drawer for storing valuables such as my glasses (lost my last pair forever down the side of an AB seat). It was the best business class flight experience I have had in the last year and a half and I rated it above the carriers bracketed above.
