If you want a Sybilla more for every battle in existence then you need to rethink a little. That said, i am not going to argue the usefulness of either, i know a princess will serve well in many cases and that it is one of the better starters you can get. It's not like this spotlight is very good for beginners in general though. Of course, he could get lucky and get something not in the spotlight, chances aren't increased tremendously after all.

All in all, up to him if he can be arsed.
