Is it better for overall dps?
Logically it seems better for overall survivability, but armor pot is probably still better on a burst damage phase fight like ursoc?
P.S.
You can find the sims for the pots in the dedicated fury thread. Need to scroll back a few pages.
For protection it is definetly usefull for survival - since str = ignore pain scaleing. It might not be best dps wise but becauae it last for 1min it can be used as a mini defensive cd (shades of tarannar) was particually good for example.
I'm definetly going to keep using it - you can look up Falck-ragnaros if you want to see the results for raiding (can't link)
