It all depends on your cable routing and frame geometry.
A top swing derailleur has the seat tube clamp placed low and the derailleur sits on top of it. A lot of full suspension bikes with an interupted seat tube use this type. A bottom swing has the clamp up high and the derailleur kinda hands down below the clamp. A standard triangle frame utilizes this type.
If your cable routing goes down your downtube, around your bottom bracket and then up, you need a bottom pull. If your routing goes along the top tube and down the seattube, you need a top pull.
