It depends on what you mean buy better. A 4-link is an upgrade from a ladder setup as far as adjustability. There is like 132 different combinations. That makes it better, right? not exactly. It does if you race for a living and race at many different tracks and conditions. But if you are an occasional racer and stick to only a few tracks I would say the ladder bar is better because it is easier to set up correctly and adjust. It is more foregiving if the setup is not quite right. 32" is the popular ladder bar length.
