In my experience, the most productive teams are a mix of people with widely differing skills combined with good relationships, good communication, and a lot of mutual respect. I worked alongside a true 10x (or maybe even 100x) developer on my last job. It was astounding to watch his code changes on the order of 500-4000 lines (mostly front-end JS/TS/HTML/CSS) roll in day after day after day for years -- most of that being new code that implemented planned features and worked. He wasn't really a systems thinker, and he wasn't super big on abstraction, either. But we had 2 other developers who were extremely good at refactoring, abstracting, systems thinking, etc., as well as 4 rank-and-file devs who got their work done. We all filled in where others lacked, and it was an incredibly effective team. My point is, "10x developers" do not exist in a vacuum, and hiring people strictly for past productivity in a particular environment is fallacious. Instead, try to craft a "10x team" where each person brings something helpful to the table, everyone works hard because they want to, and there is an environment of supportiveness and great communication.
