Well, I typically only see two Admiral's clubs. LAX terminal 4 and DFW terminal B.

DFW B is very nice. The one in C is nice, and the recently re-done one in A is very, very nice.

However, LAX Terminal 4 is showing its age. But I almost always plop down at the bar for a drink or two and to chat with the regular bartenders. But I'm really looking forward to the new one opening up down by security.
