Amex & Diners charge merchants higher commission than Visa & Mastercard IIRC.

Also they are slower at paying up the retailer who has to set up separate
merchant accounts with Amex & Diners. The rest (Visa, Mastercard, all the
debit cards etc.) usually all come under one.

Of course Amex & Diners card holders (or "Members" as they prefer to be
called) come out with the statement "The perks are much better" as a
standard response each time this point is raised.
