I had always wondered about the various manufacturers and appreciate the complete rundown on your new and old seats.
FYI, I flew on N767UA FRA-ORD in (then) Connoisseur Class and I really liked the older SICMA Business class seats, but some of the maintenance guys around here (Bay area) said they were a headache mechanically and electrically. That being said, SICMA enjoys wide popularity so I'm not sure what's going on. The new BE seats are nice as well. The new Delta Business Elite seats are also BE, as are the AA business class in the 777 (perhaps other a/c as well).
Recaro is really getting a lot of orders for YC seats, especially for long-haulers, from UA, AA (A300 and 777) and Swissair (all the new Airbus lineup). They must be doing something right.
FYI, for all seat fanatics, BE Aerospace has its own website (listed on Yahoo) and is worth a look just to see some of the latest product.
