There are some who prefer the Transition car, and some who do not like it. It is always a Superliner II, so the ride is better than a Superliner I; and there is no enclosed closet in the Roomettes, so the storage space is more versatile. Also, room 22 will be on the north side of the train, which I think has better scenery and definitely has better lighting.
(The Transition cars are so named because there is a stairway at one end for transition to single-level cars, so Transition cars are always oriented in the same direction and one can predict the side on which one's Roomette will be).
