I only have two knives (both folders meant for work) that are partially serrated. The only reason I'd choose a serrated knife over a plain edge is if it were going to be a knife that wasn't going to get sharpened much for whatever reason (in my experience serrated knives continue to cut for a really long time) and I was going to be cutting cordage, rope, seat belts, fire hose and the like. In other words a rescue knife. If it's not for something like that go with a plain edge. Plain edged knives are easier to sharpen.
