DT DRG Stats Priority

[Prishax]

I didn´t play much endgame after EW MSQ but now i´m playing for real with DT...

I compare DPS currently via fflogs and comparing dungeon boss dps from other Dragoons, to keep up with the standard/max potential. While Dragoon is kinda rare in the rankings/logs i saw some Dragoons who have lower gear than me and the only better stat is crit(like 300 more crit) on them, still they do more average dmg on many skills(Even after recreating their rotation).

So is it actually better to have less strength and more crit via green gear?

And what is the stat priority(materia included)? Crit > Determination?

All i know is that Dragoon doesn´t need Speed(i never saw one using extra speed materia/stats too). And i also remember reading back then that direct hit is a bad thing to go for.
