BOS and DCA are essentially Admirals Club in heritage, CLT and PHX are US Clubs. They have been merged in terms of offering, so it's all the same in that respect. PHX has several clubs scattered around, one of which has been upgraded (but I didn't realise that it had been, it's not a SIN style upgrade!), but none are big or impressive really. CLT has a big lounge with impressive views, plenty of space, all sorts of nooks and crannies. BOS is medium sized, no views, not good not bad. DCA has a bit of a view but is high up. The staff there are extra good, and that is from a high baseline too. Not much space, but it's not that packed when I'm in there, and DCA is fairly compact so easy to nip in and nip out.
So in short, CLT for roominess and views, DCA for good staff and being near the gate. CLT is a great airport generally.
