I use Alden Leather Defender on all my AE shell shoes as well as Alden and Carmina shells. They are all from Horween so there's no reason why it wouldn't work on all of them. I like the results.
As for AE shell cream, I do have a jar of burgundy ones that I use on a pair of burgundy Bradleys about once a year. I use Alden paste wax or Saphir cordovan cream on the other shell colors though. I think all these products are fine and work. It just depends on what you feel like using.
