I would go with non serrated. Once I learned how to at least put a descent edge on a knife, serrations have been a pain in the ass to me. The dont cut clean and are a bitch to sharpen. Keep your plain edge sharp and you should be good to go. Color is whichever one looks better for you. I dont beleive this knife comes in a satin finish, but they do have a grey colored coating, which is what I think you are referring to. So it brings you back to which one looks cooler to you.
