Top or bottom driven - which is better?

I've been in a quandary lately.  The last 12 years of my professional life have been in organizations that are top driven.  By that I mean if you think of a triangle, there is a leader at the top that establishes a clear vision and that guidance comes down to managers, down to workers, etc...However, I currently work at an organization that instead primarily works things from the bottom up.  In our current case the workers push up many ideas based on what they think are important.  There's a place for both concepts, but is one necessarily better than the other?  With ideas coming from the bottom of the triangle to the top there's room for duplication of efforts and a perceived or real lack of clear direction for the organization.  

I've had the opportunity to work for micro managers and the polar opposites of micro managers and after working for both, I've come to this realization.  I work better in a top down organization.  I've found my best successes in an environment where leadership provides some broad overarching goals but doesn't tell you exactly how to get there.  In this case you understand where leadership wants to go but gives you the opportunity to define the route you'll take to get there which ultimately can lead to new and innovative solutions.
