We switched from a square hopper to a circular hopper after running into a lot of issues with frisbees not stacking particularly well in the square hopper and jamming the feeder. Square wasn't the way to go for us. I think the more sides you have keeping it centered the better, and a circle has infinite sides.
Drawbacks: the circular hopper is tempermental to any pinching, so you have to be careful to keep it round with any attachments or fastening.
