Anything with an additional MAB +3 or higher will be a slight upgrade over Teal Saio or Genie Weskit, though +3 itself would come close to even with BLM's AF3+1. SCH's AF3+1 very, very clearly wins. An augment of MAB +4 or +5 will beat out BLM's AF3+1. Thankfully, BLM's AF3+2 still wins overall (well, except for SCH...).
