Hmmm. I'm surprising myself here and will go with
London.
Paris is too tied to
Paris Hilton for me (I was right in the generation of 'The Simple Life' and
Paris everywhere on everything) and also the image of
Paris is all romantic and too loaded for me.
London is not a name I'd EVER use and would actively discourage someone I knew from using it but I really do like the city (I like
Paris too) and I have some very special memories in
London. It's also a strong name and I like strong names on girls.
