In some areas of the US AMEX is routinely rejected witch makes it less valuable as a go-to card at home. The Sapphire seems to be filling this slot to some extent. Also more of a west coast item is the Alaska card- overlooked I think. 40K and a companion fare with no spend, a BoA card so doesn't interfere with the Chase collection, and mildly churnable. A lot of excellent partners also.
