Threatening Roar is better. NEXT QUESTION.
...Oh fine, you want more reasons? Picky-ass kids, I tell ya.
Threatening Roar has one massive, massive, massive bonus over Negate Attack.
Threatening Roar can be chained to things other than attack.
Opponent summons Ultimate Ancient Gear Golem? Threatening Roar. Heavy Storm so they can attack freely? Threatening Roar. They activate some sort of one turn power-up for one of their monsters? Chain Threatening Roar. Pitch-Black Warwolf? That ain't gonna stop Threatening Roar. Try to tune with Trapart? Threatening Roar.
So yeah. Run Threatening Roar, not Negate Attack.
EDIT: 'cept in counter angels, 'course.
