Metal cutters....Better shapes and sharper cuts!!
I like metal better...but i cant always afford the metal ones soooo needless to say i have more plastic than metal..
I like the metal, because yes, they are usually sharper/cleaner cutting.
But I also like some plastic ones because they keep their shape perfectly over time whether dropped or shut in a drawer that's too full of other cutters! 
The one thing I DON'T like about the plastic ones (sold by Wilton especially!) is the plastic strip they put across the top of them...so I can't use doughs that are any thicker than my cutter. 
I also don't much like the plastic ones that make impressions/patterns on the dough as well. The cookies are always too thin and I prefer to make my own designs instead of the cutter making them for me.
