Im assuming you mean Slugga's and Choppa's? (pistols and axes)
Probably lean towards Goffs since you've already got a heap of boyz with Choppa's. Deathskulls would be my second choice for the rerolls. Bad Moons favor more shooty Orks so I don't think they would be great for those models.
but im brand new myself so take my advice with a pinch of salt.
