I've read lots of comments about Ungaro III being similar to Zino. Is this true? If so, how are they similar? How do they differ? For the record, I'm not interested in vintage here at all since I own a bottle of Ungaro III that's relatively recent and I love it, and I'm debating picking up the current version of Zino.

Zino isn't expensive on Amazon. If I own Ungaro III, is it worth buying, or is it redundant?
