I personally feel you could go either way.
If you are really a collector, you could add it to your collection, it is worth adding to a large mandarin variety collection (of all the best varieties), but I would not be too anxious to add it.
I do think Lee x Nova is better than Dancy or Gold Nugget though, if that helps at all. It's sort of a standard, very slightly sour flavorful mandarin, a little bit of tropical mandarin flavor, nicely sweet but not out of the ordinary so.
