The point is not that girl hero rescuing boy damsel is more interesting, it's that this would be an interesting subversion of the prophesy core to the Zelda mythology. If Link fails early and it is Zelda who has to step up and be the proactive hero, that's a subversion not just of out-of-game tropes, but in-universe tropes as well. Zelda would have to face someone else's destiny, and challenges which require someone else's skills. The bad guy could even have underestimated and ignored her specifically because historically (or mythologically, it's hard to tell which in this universe) it was the other hero who was directly responsible for the prevention of evil.

Fundamentally, it's interesting to see someone thrust into a situation they aren't prepared for, to build skills and face challenges which are unusual to them. In Breath of the Wild, Link is an experienced knight, a personal bodyguard to the heir of his nation's monarchy. There is no one in the world more fundamentally prepared to pick up a sword and slay goblins and traverse dungeons to save Zelda. It's been done. It would be interesting to see someone who is the least prepared to play that role (because they've been preparing for a different role) take a shot at it.
