I think the name Luca is nicer for a girl. On a boy, I think it sounds too femenine. It can also be used (on a girl) as a pet form of Laurence, Lucilla or Lucania. Luca May has a nice ring to it.

Also a feminine name in Croatia, quite common, where it is a short form of Lucija. Variant form is Luce. [noted -ed]
My little niece is named Luca. It is a very sweet name. It's pronounced as Lutza, not eaxctly, but that's the closest I can come describing it. It's a cute name in Hungarian for little girls and also in English/German/Italian for little boys.
