Simulation and theorycraft can only do so much. The real question is, how do you actually perform with either set?
This source shows the 2pc is worth about 1k dps:

However, the increase in item levels will more than likely cause you to perform better a majority of the time. I don't know MM stat weights of the top of my head, but usually they are pretty even. 76 agility + 117 secondary stats is a large chunk and is probably about 500 dps on its own.
So proper focus management at 100% efficiency nets 1k dps vs 30 ilvls in stats for a comparable gain + survivability.
Again, how well do you actually perform?
Best method is to try both and see.
Edit: Also, longer fights favor the 2pc more as you'll get more focus by the end to use more abilities. Raw stats typically favor shorter fights and AoE. Spending time focus capped due to switching targets or moving without a target hurts the 2 pc.
