There was a brief period back in 2016 just after release when the Rift didn't have tracked controllers and the Vive did. That lead to Vive being the fan favorite for quite a while afterwards, even once the Rift finally did get 6DoF controllers a few months later. A lot has happened since then; the landscape today is completely different.
