SkyTeam - Best SkyTeam lounge in JFK T1?

What is the best lounge in JFK T1: Air France, Alitalia, or Korean?

I will be flying Alitalia in J and have Delta GM, so should be able to access any of those lounges. I will have 2 travel companions, who do not have any SkyTeam status.

Thanks

Air France is the best

Depending on when you are flying, some lounges may be far less crowded; when the early AF flights go out, for instance, the KE lounge is often empty. If you have two companions, however, don't expect to get both of them into the lounge; your Elite Plus status only permits one guest.

Air France is the best

why?

I don't know if this is standard protocol, but I was denied entry to the KE lounge at JFK T1 because I was flying AF. It was last July...I flew JFK-CDG in Affaires class..but they still wouldn't permit access...despite my being a DL Gold Medallion, hence SkyTeam Elite Plus. I ended up at the AF lounge, which is quite nice. AZ lounge was closed...surprise...

They are all unmemorable.
