Do you mean Strong DBL Action with fully bent at the end or do you mean Strong Single Action with a slight bend?

As far as clubHEAD control, both are just as good at preventing throwaway, because if the wrist is slightly, or fully, bent at the top, but flat at impact, it must be moving from a position of throwaway (bent) to not throwaway (flat).

That said clubFACE control would require much more 'effort' without a pure swingers Rhythm (in which case, grip and top of swing position matter very little because CF aligns the face for impact). The advantage is that you can reach the 'limit' of FULL roll and not worry about a hook.
