I know that the hunt for "the best", "the stiffest", "the smoothest" can be alluring. But, just know that most (all?) but the top athletes in the world will push a set of quality cranks to the limits and experience any differences in feel or performance.
Cheap cranks will always be cheap cranks. They won't fit well, will have gaps, will have crunchy bearings, and may loosen over time. But, at the higher end (like the ones you mention) they all perform very well.
I've had crap, no-name brand cranks (the kind that come on entry level bikes) have arms that migrate off while you ride. But, not on any of the nicer cranks.
