-hp +atk or -atk +def myrrh?

i'd go for the +def/-atk. her weapon gives her +3 attack and with buffs she can make up for that attack bane pretty easy. think of her weapon as turning her defense stat into a psuedo speed stat. it'll help keep her from getting doubled a lot.

Not an easy choice. It all depends on your build choice and team options. With an optimized build and emblem support for the +def IV, I imagine that she could reach 50 defense, which would make her quite difficult to double (due to great flame). But then again, with the same support, you could reach similar amounts of defense with the +atk IV.

On the other hand, the +atk IV would deal 12 more damage on enemy phase encounters thanks to quick riposte, which is huge. Due to that fact, I'd actually opt for the +atk IV, but take my words with a grain of salt, because I don't have Myrrh myself.

Gut tells me +ATK/-HP. It's 3 defense vs 6 attack. Def Tactic (seal) or Fortify Fliers gets her to 42 defense which is good. I mostly use her to counter low defense ranged units anyways, with Distant Counter in the A slot.
