Lack of pockets and printed logo are downgrades with the new ones.

The biggest issue for me is actually getting the pajamas. I like to change into them before takeoff and am usually one of the first to board, meaning that we could be 45+ minutes from departure when I ask the FAs for a pair. No matter how deferential and obsequious I am when I ask, they always communicate verbally or non-verbally how busy and annoyed by the request they are, and that they may or may not get to it before takeoff.
