John ,
You are rating apples and oranges. The Blue and Clear products are not co-branded as the others on your list.
All the co-branded products fall below Amex products because they are not handled by Amex customer service or UW.
And in turn , all Amex charge cards come above the Amex credit cards. (possiblly because they are all about service and the others are all about interest.)
I have several cards from Amex and from the time I got the second one, I noticed on the website when I am logged in to my account that they are organized from top to bottom in the order of importance as Amex sees them. Not Alphabetically or otherwise.
