I like Delfino, but Moon is more consistant: I rather a guy who does a few things in a consistant basis than a guy who can do a lot of things but no all the days.
How do you rate Delfino? Looking at his bad days or the good ones? If you look at what he can do in a consistant basis, he isn't that better than Moon, he just can give you somedays some extra things.
IMO, there is nothing worse than thinking that you have what you need till you look for it and discover you hadn't it.
