I will write only PvE perspective:
Elondrian Bulwark
- 100% chance on proc when charged (3 targets, armor and crit debuff, counterattack), 5s duration (not stackable)
- chance when being hit on armor buff and heal over time (25s hidden cooldown) - skip to next player after 5s
- looks like branch of the tree
Frost Bulwark
- Icy Spikes (high AoE dmg), after Spikes you get armor buff - high proc rate
- armor debuff - high proc rate
- looks really cool
If you want to use Elondrian Bulwark, you HAVE TO charge your normal attack (its big advantage when you incorporate it into your skill rotation - high chance on stun when charged, but disadvantage is only 3 targets). Defensive point of view - you get armor buff once per 25s and buff duration is 10s (thats 15s between proc).
Frost Bulwark has really high proc rate (higher than Maul!). Icy Spikes has AoE dmg (3 waves in fast sequence - help maintain aggro). You get 175 armor (not stackable when you get several proc in a row) buff after Spikes are gone - due to proc rate you get armor buff more often than with Elondrian Bulwark. Armor debuff is separate proc with high proc rate as well. In elites I see procs almost a whole time. Frost Bulwarks proc has no hidden cooldown.
I choose Frost version, make your own choice if you want:
