it depends on your preference. This is the way i see it, and my reason for using protector:
> I would choose garment if my force is ice, since I won't get hit much often.
> I would choose protector if my force is fire, since I can't slow enemies down, I might as well prefer the extra physical defense of a protector. Also with the fire buff, i mastered the magic resistance buff (fire protection series?) wherein I have more defense against magic attack.

I also mastered the fire shield (I always carry a shield with me in the inventory) to further reduce the abnormal status (e.g. slowed, forzen, frostbite, poisoned, shocked, burn).
