Actually, I think Yuzu does have standout area(s), in fact many of them. Maybe he has so many standout areas, it seems like he doesn't have any?
1. Jumping prowess: his quads (and 3A!) are more effortless than anyone else's jumps in the world. Boyang and Nathan have the 4Lz and/or 4F, probably their only advantage over Yuzu, but I dont think their jumps are more beautiful than Yuzu's. Yuzu's jumps are fast, effortless throughout, with extremely good air position, and transitions into and out of them. If the only thing that goes into jumping prowess is having a 4Lz or a 4F, then...well...I disagree.
2. Intense performances: I don't think Seimei is less intense than Loco. And it's quite a ways more intense than Winter or Turandot ATM.
3. Superior skating skills: I know Patrick has good skating skills, but (if you haven't already guessed), IMO Yuzu has almost as good skating skills and arguably as good -- their skating styles aren't exactly the same, so it's hard to compare, but Chopin showcases his deep edges, flow, and speed, and you just have to see how well he times every element and every turn with the music (which mind you changes speed like 50x) to realize what great control and skating skills he has. To me, it's way more attention grabbing than anything Patrick has done (he tends to skate to kind of similar, one-note music), but hey that's why I'm a Yuzu fan and not a Patrick fan.
...If Yuzu's level of skating skills/jumping prowess/intensity is not enough to grab a judge's attention, they probably didn't want to pay attention anyway.
ETA: I'd also like to add: spins. Yuzu's spins are above and beyond everyone else's in the top 6.
