'Full' crits vs partial crits on SS are irrelevant, even during burst windows.

Unless you're concocting some magical scenario where you only get to SS/CS once, if it crits you win and if it doesn't (or you get a partial SS) you wipe. In which case, sure, CS is better. But you're still wiping 75% of the time, so who cares.
And in fact 3 random rolls vs 2 random rolls, the 3 rolls is less random as the more you roll the quicker you'll trend towards the average.
