First, get your bodyfat measured for real. The bodyfat scales are not accurate. (They may be good for some purposes, ie. measuring RELATIVE changes, but they are not accurate for purely measuring bodyfat). Go to a gym and have someone there measure you with calipers.
When in doubt, I always advocate cutting. The problem with bulking, imho, is that most guys do not bulk cleanly. They take bulking as meaning they can eat whatever garbage they want and simply get fat. In bulking, you want to add muscle mass and keep the fat as low as possible. When adding muscle mass, you'll necessarily add some fat as well so that is a given, but you're not looking to "get fat" you're looking to get muscular.
If you're truly under 10%, you may want to bulk. If you don't know if you're ripped, however, you probably aren't and should probably cut.
That's just my opinion, though, a lot of guys on here are going for that big look at any cost. Me, I'd rather be ripped.
