Brilliant Star Trek vs. Star Wars trick in the New York Times crossword puzzle

In Sunday's New York Times crossword puzzle, constructor Stephen McCarthy embedded a wonderful trick centered on the Star Trek vs. Star Wars debate. For the clue "The better of two sci-fi franchises," either answer works. From the Constructor Notes:

I am a fan of both "Star Wars" and "Star Trek," so it's nice to be able to highlight both (not to mention the friendly rivalry between the two fandoms) in one puzzle. I grew up with the second iterations of both franchises (Episodes 1-3/The Next Generation) and had a crush on both Hayden Christensen as Anakin Skywalker and Wil Wheaton as Wesley Crusher when I was a teenager, so I couldn't decide which franchise I liked better!
