Which is better overall?

6 GCD = Midare (using the 2 GCD AOE skills + 2 button Yukikaze + Hakaze)
or
8 GCD = Midare (the normal rotation?)

One seems like it's faster and still gains the buffs, and thus you execute Midare quicker and build-up meditates for Shoha faster, but the other is single target centric and thus does do the intended damage before Midare is executed, but again it seems like its slower to build up Shoha. What do you pros do?
