Yeah, mostly in places where climbing is awkward. Examples that come to mind immediately—the daily with the guy from Liyue who doesn't remember where he left off with his story. To get to him from the teleport, you either have to climb a crooked wall or walk a kilometer via stairs, but it's much easier with Keqing.
And just flying up to cross a river/ravine is also cool. Of course, you can do that with own grandpa's pillar/Albedo's lift, but it's not as convenient. Plus, Kazuha can press his E in flight on cooldown.
But I forgot about the mujina) If you just need to run more or less far somewhere, then she is the coolest, yeah.

Pulling for Ayaka ahead of the banner. I'd love to get C2, but I can only scrape together enough for C1, which isn't really needed. Better to try for the sword on luck—especially since it's OP for Keqing too.
