I've heard it said that you always pick a piece of gear with more "Strength" on it. Is that always true?

I have these two gloves: https://imgur.com/a/kLF3ZBW
(Note: Imagine the one on the right has two Crit + 40 materia slotted)

Which glove would a Dragoon be better off using? Is a 10 Strength difference that big?
