It's subjective really, they're both a great pieces but if you can't obtain the 3 piece requirement to get the +7 STR on at least the bracelets I would consider otherwise, but then again my setup is more melee oriented.

Yes the gloves and Cutlass are listed mostly due to their accuracy bonuses which is helpful for instances like Garuda when you'll likely need it. Since you'll likely be below the STR cap however, a Giantsgall Longsword melded with STR, MND, or Enmity would probably wield greater benefits and damage potential than the Cutlass.
