In my opinion the Wing and Pier business lounges are not that great. Possibly because they are connected to the First lounges.
The Cabin and the Bridge though are OK. I love to sit at the bar in each of these 2 lounges and have a vodka and orange looking at the views of Hong Kong from the Cabin and the gates/taxiway from the Bridge. Very relaxing. Also they are located between the Wing and the Pier and good to break up the walk.
Have you been to the new Pier J? Still don't like it?
