Again, you are running sim craft, the probability of you actually hitting and having that even matter is so slim that you are never going to benefit from it enough to out weigh the other options vastly. Because that assumes
-your target lives long enough to get that extra swing in
-your target is within range to get that extra swing in
-You are hitting your attacks perfectly, and not getting a GCD before it
-Your target is not immune or in a boss transition
Its not going to matter enough for 90% of the players skill level to ever mean anything.
Just pick the one thats fun, and more enjoyable to use, or if you like their xmog and just have fun with the game. The only time this is ever going to matter is on raid difficulties most people are never going to deal with. And here is a news flash, to most of the people that this DOES matter to, they dont care about anything else but min maxing because thats fun to them. Its why they pick the best races to do x, on class Y.
