Zaku, Green or Red?

I'm having a dilemma right now. I feel that I must have a Zaku because it is such an iconic mobile suite in the Gundam World. So decided to choose a Regular Grade for it. But now I also have to decide between the green or red Zaku.

Personally I prefer the red one because it looks cooler, but then again the more iconic one is the green Zaku. What to do, which to choose? Any suggestions?
