Question [Q] dsxda Kitchen, updater or update-script?

Hey guys, just a short question, I am just trying to cook "my own Rom" and therefor I am using the Kitchen. When I wanna build it and also at the very beginning, I am being asked, if I wanna change updater-script to update-script.
Now 1. Should I change it?
2. Whats the difference between em?
Especially at the beginning, since this probably changes most...
Sorry I am still Noob and I guess I still gotta learn a lot here
-edit- It's all about v20n btw
