Just wanted to come back to this thread and thank everybody for helpful info.....
My trip has come and gone...
Ended up taking Affaires on the outbound, Premium Voyageur on the return. I found neither seat to be particularly comfortable, though both had plenty of room and were very stylish. The Affaires menu and service was great (the former certainly the best Ihave experienced on a commercial flight. Interesting note on the P.V. seat...I noticed a funny in the AF promo materials....they have a video of this guy who checks in very pleasantly, goes to the lounge etc...then he gets into his P.V. seat, and, right there on the video to promote the service, he clearly has difficulty finding a comfortable position. It's as if they told the actor "sit down and get comfy" and he adjusts his head and body repeatedly while the camera rolls. Anyway, I found the seat very nice, plenty of space, but, not unexpectedly, very difficult to sleep in.
Thanks again all.
