If the ("plebeian" side") lounge stays the same as it was before the November maintenance closures, then LAN's lounge is a bit better than the Centurion Lounge from Amex. Both are still great choices, and I'd choose depending on how full they are, first checking the LANs one.
For my next trip, I'm contemplating a "treat" and going to the special AX lounge. Have you been in since your original visit? As you know, in EZE, LAN doesn't serve the usual Roederer, so the only very good lounge bubbles would be the AX Voov Klikow (not that LAN's Baron B is bad). That, plus a shot of JW Blue and a cooked meal (prior to what will likely be an unsatisfying AA F dinner) sound like it is worth $50.
