Via a search, you'll find a thread that talks about the effectiveness of different ball controls. I believe the thread is called "All about Ball Control".

I've seen plenty of the robots that done extremely well while pushing the balls. Teams 1466 and 34 only pushed the ball at Peachtree, they were pushing in 6-7 balls a match.

Really depends on what your ultimate goal is. My team has spent the better part of 2 months working on different ball control mechanisms because our design depends on it.
