I love the name Nefertari. It sounds close to the name Nefertiti, which gives it an exotic appeal, but at the same time it seems calmer. Nefertari is a good name but I'm not sure if it would make a good first name.
Unlike a lot of other "long" names, I don't think Nefertari has an "elitist" quality at all. Okay, maybe a little. But it has a really pretty sound. And I don't think it has *nearly* as much bullying material as Nefertiti.
The only Nefertari I've ever heard of (besides the one in the name's entry) is Nefertari Maharassa, a fictional character in the webcomic Friendly Hostility.
