.. except, I suggest (
if you are a drinker

), the booze is virtually hidden on little carts in corners and quite limited selection.
For me, best lounge is where you can just relax and do what you want to do at that particular time in peace and comfort - including (at different times) ... working at laptop; making calls; having a nice meal, good quality booze, sitting idly and looking out the windows, having a snooze, sitting at a bar chit-chatting to barperson.
For me, the one that satisfies most criteria is the Pier First at HKG, at least before covid. A nice comfy environment to be in.
Closely followed by The Wing First at HKG again, before covid. Cabanas and Champagne Lounge were highlights.
Of ones I've been in recently, Al Safwa First at DOH is the best. Its a bit cavernous at first, but once you understand the nooks and crannies, its a great space to spend hours in, if necessary. 6 hour sleeper rooms, each with shower etc; great restaurant with very premium wines etc etc. Lots of different spaces to do different things. Direct access to planes via lift.
Honourable mentions:
* IST J lounge - booze selection and availability is the negative. Great food selections and various spaces. Lockable bag lockers ares great if you want to go for a walk in the terminal.
* SIN The Private Room. Great food and bev selection, great attentive waiter service. A bit small (understandably); sleeper rooms only for 2 hrs and bed-only; people can look through the tinted glass panel in the door (as they did!!)
* Qantas SYD F Lounge - often crowded and noisy, limited different spaces. Great food service, great views, spa
* DOH Al Morjain J - can get very crowded, and wait for showers, but hopefully alleviated by the opening of their additional (huge) lounge. Two different eating areas.
* DXB F lounge A long time ago, but I recall one of the best steaks I've had in a lounge, but overall a bit sterile
Haven't been in - Concord Room, AUH F, FRA FCT

My best Aussie domestic lounge - Perth QP.
Did someone mention HBA QP? Absolutely the best lounge for demonstrating everything that's bad in a lounge - perennially crowded, lack of amenity, grubby (male) toilets ..... Ugh.
