Tyr Doombringer,2HS or Dualsword????

I had a Tyr Doombringer lvl 86 and my election was 2 handed sword,caused Berserker and Doombringer have passive with 2 handed weapon. But when i reach lvl 95 (maybe in a few time) i dont know which weapon i put to the char. 2 handed sword or Dual sword??? Which 2 of those are more viable for Tyr Doombringer???? I prefer 2 handed sword but i see a lot of Tyrs using Dual sword including Titans so thats my doubt.
