I totally agree, it's much more Yoru defining the current meta than Tejo. And it's not necessarily because he's stronger than the other duelists, (although he probably is also that given how versatile gatecrash is).
I think the biggest factor right now is that there are so many good agents you can't fit everything into one comp, and Yoru helps to alleviate that by putting Entry, Flashes and a very strong info ult on one slot so you can run strong agents that don't check boxes in your flex slot without having to make big sacrifices.
Making up for Haven Iso, Deadlock Split, and the poor info of Breach/Tejo comps are the most obvious examples of this.
Or if you're KC you miss the "strong" part entirely and he's making up for the Harbor
