I like the look of Cage armor, but the Drifter set is my absolute favorite armor in the game. If it only had higher stats or took ballistic weave. Lately I've been giving Cage armor or Spike armor to my settlers, as mentioned above, or giving it to my companions. Piper looks really good in it.
edit: Spike armor has some of the same design elements as the Drifter outfit but with a little better stats. I really wish those armors could be up-graded, considering we have the right perks, etc.
