What are the upsides of these specs?

[Dayon]

Now, there are two mainstream tanking specs, that I've noticed, for a Warrior to use.

There's that 15/5/51 Deep Wounds spec, and then that 5/8/58 which I myself am partial to.

It's obvious that the Deep Wounds is a more damage-producing spec, and the latter is something more of a spec chock full of neat stuff.

My question is if one spec is truly superior to the other in terms of threat or survivability.

It would make it little bit easier if you linked the second spec.

Edit: Did some searching and found this "5/8/58" spec. It's little odd because it seems to be labeled as survivability spec but has whole 5/5 Cruelty for fairly insignificant threat increase.
