I just visited the new LAX club for the first time and it has moved to the top of my list. I use SFO, DCA, IAD and EWR regularly and I think the new LAX is currently much nicer than those. In LAX, the size, the overall layout, the windows, the lighting and just the overall feeling are all good. I have not seen the new ORD club(s), so can't speak to those.
