I really can't say, as it does comes down to the look of your place & what you are going for. What I can say though, is to make sure you use a really good exterior paint, with UV & mold inhibitors in it
I'd say stay away from any gloss. Go with a satin or matte type finish. The shutters are meant to enhance the windows, create a bigger footprint on your house, not stand out so that that is all anyone sees.
