I think the black silk screen looks fine, it does its job, which is to make assembly and debugging easier which is the mains thing.
If you're bothered about looks, use the old phenolic impregnated paper PCB which looks better with a black silk screen. I don't use fibreglass unless I really need to because it's more expensive and harder on cutting tools. I don't see why fibreglass is so popular, it may be stronger but I find it more difficult to work with; phenolic impregnated paper is fine for most applications.
Here's a couple of pictures of a board I made awhile ago.
