I would say that depends on the situation, if its an easy dungeon where you can survive without problems then bm3 no question. But since bm3 leech is waaay worse than bm2, some dungeons might be easier using bm2 if you have trouble surviving.
BM3 = more dmg less def
BM2 = more def less dmg
Try BM3 everywhere. If you feel you die too much, switch to BM2. That's what I did =)
