This talent just seems miles ahead of the other two, especially with artifact talents.
It makes it so BoF only has a 9s CD which means you can basically keep the 8% less damage up with the artifact debuff almost at all times. That alone makes it worth it over the other 2. Now combine it with the fact that Blackout Strike is on a 2.5s CD or so (after haste), you'll be taking advantage of this talent on almost all of your abilities.
An extra 2s off of ISB/PB Cd with KS, 3s pause on stagger damage with ISB, stack of mastery with PB are all great buffs you'll be getting.
Not only that, I think it makes the rotation a lot more fun and dynamic.
