For me, the view is almost more important than the amenities. Therefore DFW AA Terminal D lounge is high on the list, likewise LHR BA F T5 and of course SYD QF F T1 and NZ T1. There are others (of course). No view, no good.
I'm with you on that og. Airline lounges can be quite uninteresting if you can't get up close and personal to those jets.
Some hotels, such as the top floor of the Melbourne Airport Hilton, can be good for the same reason.
