Well, the two words have a somewhat different meaning. Nude implies being without clothing in a setting where it is entirely appropriate, such as a nude beach, a nude resort or a nude swimming pool. Naked implies being without clothing in a setting where it is not so appropriate, such as walking down a city street.

Which do I prefer? I like both. It's fun and relaxing to be in a place where no clothing is worn and everyone is free and open. It's exciting and exhilarating to be without clothes elsewhere, where I am the only naked person and am the center of attention.
