I happen to teach in a university with time based media and film departments and I can assure you that among the next generation we have reached 50/50 Premiere/Davinci as NLE. I try to do one small editing project per year in Davinci and while Premiere is still better with material-intensive projects, davinci is is totally usable and comes with its own upsides. And thry have improved gradualy throughout the past years, so I expect them to catch up there. As for Blender, I was a Maya user before and never really looked back. Blender is also gaining a lot of traction in the recent years, especially since they introduced the Eevee renderer and decent grease pencil/2D animation workflows. I can't speak for all segments of the professional market, but Blender is good enough to earn a living with it, while not feeling you are trying to paint the Mona Lisa in paint, as of now. And more importantly: it is improving at a quicker pace than most other software and that includes commercial ones.
