Barbarian or Berserker?

Here is a comparison of Barbarians and Berserkers.
Would like to read your thoughts about which you find superior overall.

BARBARIAN
Advantages:
- Rolls d12 for HP instead of a Fighter's d10
- Moves 2 points faster than the normal character movement rate
- Immune to backstab
- At Level 11 gains 10% Resistance to Slashing, Piercing, Crushing & Missile Damage
At Level 15 gains 5% more DMG Resistance (Total: 15%)
At Level 19 gains 5% more DMG Resistance (Total: 20%)
[With the HLA 'Hardiness' and the 'Defender of Easthaven Flail',
Total DMG Resistance can reach 80% / Missile 60%]

- Can use Barbarian Rage 1/day for every 4 levels (Levels 1, 5, 9, 13, ...)
Rage lasts for 30 seconds
Rage gives +4 to STR & CON
Rage gives +2 to Saves vs Spells
Rage gives immunity to "ALL" Charm, Confusion, Fear, Hold, Maze, Stun, & Sleep
