If it is high rate of rewards that you want most. Pick from AMEX Centurion, Citi Chairman, and AMEX SPG. If you want certain status or benefits, pick from the other cards above. If AA is your favorite airline. You should consider AMEX SPG (highest reward rate), Diners or Carte Blanche. They are the only ones that transfer (other than Citi AA MC).
