Although I heard good things about DX, I generally avoided using it because of its whiskers. Plus I do not really want to trade the range spec over melee spec. Personally, I tend to not notice the difference between Tiffa's Prayer over Zero System. But if I must say it, I prefer search distance and radar over agility and booster extension. Plus damage maximize and aspd is good. As long as you don't get damaged that much (and careful not to get spec'd), then Zero System is good.
