All 3 of them are *worlds* worse than the WH/EWH passive relic though so there's no real option otherwise: if you're not using the PvP relics, you're using painfully subpar ones.
How much does your war hero relic help when tanking zorn, or stormcaller, or not tanking vorgath, or not taking damage on kephess, etc, etc, etc? Saying that all other relics are sub-par is absolutely silly. Get both, use the best one for whatever fight you are on. The factors that determine this choice are: (1) % of time taking melee/ranged hits, (2) % of incoming damage that is melee/ranged, (3) frequency of melee/ranged damage spikes, (4) farm vs. progression content.
