Best mods for Rey and QGJ?

I'm a big fan of Speed mods with Speed bonuses on my QGJ, I have almost 250 speed without his leader ability :)

My Rey is still noobish (4 stars, level 70, etc) - but I suspect she would be similar because she doesn't have any natural crit % or crit damage synergies, doesn't need potency for debuffs - so the only logical things for her are Offense (possible) or Speed. The reason I might lean toward Speed is that she has a Speed synergy with her Foresight, in that more speed = more turns, but it also = more survivability through more Foresight (the same way I mod Yoda for speed, for Foresight).

Using QGJ with a lot of +speed really helps in raids because of tm reduction from his basic.

Regarding Rey I'm not sure. Speed set bonus with protection being main focus where you can't put speed as primary. For the Triangle its either Critical Damage or Chance.
