Power user and linux power user are not the same
I am more than a power user by windows userbase standard (though I am not windows power user, I cannot do registry, windows command line and other stuff, only linux), but linux community can see me as a “barely tweaking things” person (using Fedora with ready to use DE tweaked only with internal gui, micro text editor instead of vim or emacs, etc) when power users are someone like Arch+minimal WM configured from scratch or Gentoo users
