Sadly, you're just going to find a lot of debate here. Some people say Veng. Some say Rage. Some people even like going Immortal with DPS gear and somehow think they can put out the same amount of DPS that Veng or Rage can do. And frankly, I think Imortal is just bad to PvP with, queueing solo. Beats me.
Now I know someone is going to quote me on this, but my experiences is that Veng seems to be more steady DPS and Rage is more bursty. Bursty is general better in PvP, in my opinion. Thus, I just use a Rage build for PvP and respec to Veng for PvE.
Honestly, it all depends on the player. A bad player is going to make any build terrible. Both Veng and Rage are viable in PvP. Play around with both and see what you like better.
