I would choose ..
Garment because:
-Faster movement
-MP consumption
-Less vulnerable against INT based enemies
and Protector because:
-to have a average set against both enemies (STR / INT)
-Protector is usually cheaper then Garment (if you aim on Sox last degree)
-the difference of Speed and MP consumption compared to garment is "only" 10% MP consumption / speed
Now choose what is fitting better to you
