Berserker or Valkyrie armor?
You want Berserker for typical DPS builds. Valkyrie is a set for warriors wielding a hammer or CC build… because 50% crit on stunned targets that stacks with 20% from fury is all the precision you need.

… also makes a mean truffle stew.
If you’re not trying to exploit any very specific crit% synergy (e.g. bleed procs on crit), then the crit% from Fury and general precision (e.g. trait line) is sufficient for general DPS for most setups, although you may want to split some of your gear to Berserker’s. E.g. have your weapon and [armor | accessories] as Berserker’s, and then your [accessories | armor] as Valk. You can swap your [accessories | armor] to Berserker’s if you don’t feel like you need the HP.
I’ve found that Warriors are best played in PvP as burst-dmg offensively, and damage-avoidance defensively… thus Vitality plays less of a role than Precision.
However the choice largely depends on what you are doing. PvE will demand more Vitality.
