Amex lounge benefits are now the same as Chase, both offer a Priority Pass Select, and now AFAIK offer the same number of guests. Amex also offers access to Amex Centurion lounges which are among the better domestic lounges.

Amex also includes Delta, if you're on a Delta flight.

You can still get into a Delta lounge as an Amex cardholder, but Delta has been tightening up its lounge access generally for a while. The biggest change was introducing two-tier membership; Amex cardholders, and even Delta's own top-level frequent flyers, now only get the base lounge membership (or equivalent). This shows up in things like being charged $29/person to bring guests with you, where previously you got two guests for free.

The Centurion Lounge places Amex's lounge benefits on a whole other level.

Honestly they're really only valuable if your home airport has a Centurion lounge. As much as I love Centurion lounges (and have access to them), I find myself in PP far more frequently.

Ah, very fair point. Apologies for the tunnel vision :)

Yeah, and if they're in the terminal you frequent too >.< At SFO, only T-I/T-3 (where the Centurion is) and T1-/T2 are connected airside. That said, I used to route everywhere via DFW so I could break the journey up and chill at the D17 lounge.
