Enraged Spirit vs Sustained Rage?

I'm pretty new to guardian, still leveling, but while trying to think of a decent polearm spec I just couldn't decide bewteen Enraged Spirit (from left tree) or Sustained Rage (from general). I'm not 100% sure on how the 20% increase per rank on Wrath stacks works precisely, but which of these is more useful?

https://goo.gl/AV3tyT - TANK, Melee, Full Mitigation.
https://goo.gl/zZXwXB - TANK, Melee, More DPS.
https://goo.gl/kxKJrW - Maybe TANK or better.. off tank, Spec With Battle Cry - we can improve group DPS. (I never tried it).
https://goo.gl/4y0BBY - DPS, with Volcanic Rage and Battle Cry without Storm Strike(Only CW and Flashing Arc for DPS) (I never tried it)

I think it's not possible to make good Polearm build with Enraged Spirit.

Are you searching tank build or solo one. But think for solo are important improved frenzy and storm strike combo. Something like this. https://goo.gl/TFw8q
