I was a RoR developer for 5 years and have now worked on Phoenix apps for about 6 years. The survey results have certainly gotta be at least a little selection bias, combined with Rails apps being on average older (and therefore more "legacy"). But on the other hand, for me Elixir and Phoenix really did clean up a lot of the pain points around Rails (performance, magic), while keeping the great things (developer experience, general structure), and adding some brand new stuff (channels). LiveView is really interesting, but still a bit of an experiment, from my perspective. At least, I haven't had a chance to use it "in anger" in production yet, but am generally satisfied with my "Phoenix as a better Rails" apps.
