Tolerable isn't comparable to DL, especially when you're comparing business class.
OP should be sure to check the airport terminal AR uses if an AR flight is on the itinerary. For example, my guess would be T1 at JFK with the other SkyTeam partners, but I'm not sure.If so, the lounge choices would be AF, KE and AZ. [At EZE, DL uses the big AR lounge.]
