Rear spoiler question

I like the look of a rear spoiler. And I understand most people add one for looks. But is it functional or which one is more functional?
I have a 2010 Grand Sport which comes with the Z06 spoiler. my confusion is why the ZR1 spoiler is almost exactly opposite.
If having the Z06 is functional at higher speeds why is the ZR1 lower in the center and taller on the sides.
Thanks in advance

You can buy the full width spoiler, ZR1 full width spoiler, or any number of aftermarket ones.
I personally went with the standard full width spoiler.
But if you want the most downforce, then I would think the ZR1 would be it as it is the largest but it will also create more drag.
