Turtle is a very nice format to read and write RDF in. There is no same XML serialization of RDF. RDF/XML is very annoying and unintuitive to write and parsing it into triples requires a lot of work so you need a special library anyway. You might as well start with Turtle then. That being said, it's easy to convert from one format to another: you'll get the same triples. So just use what you like.
