I'm in the same situation, and registered an account just to answer you.

As of now, I mainly do broadcast work (both with big cameras and smaller productions), and small docs/news/journalistic type work, and event type videos. But I also deliver photos, and have that as mostly a hobby and smaller part of my income, often at the same time as I do broadcast. Still enjoy it as much as a hobby/ fun income projects.
So, why will I probably go for the R6 over R5? Right now, I got a Canon XA50 for video. It has XLR, and covers my needs, for the most part. A R6 will not cover what I am missing. What I'm missing, a updated
C100 II would give me. The problem with the
C100 II is that its old and not 4K recording. It just does not make sense for me to buy that old of an camera when my XA50 has 4K. Not that I need that as of now, but still. Could of course buy a C200, but not looking to buy a
Cinema camera this year, and not next year either. Not needing RAW, and it has some other minor things that could be different.
So the R6 would for me be as a B or C camera. Right now I got a Nikon D5300, with a 16-80 2.8-4 lens. And I'm really happy with it, the image quality is great for me. Only thing missing is better low light and autofocus in video. And, for video, also matching colors and a bit more "cinematic" quality, plus dual card slots. I got that on my XA50, also a
Cinema camera will have it, so therefor, for me the R6 should have it.
Simply, I don't need, or want to know that I have 8K, 4K 120p, RAW etc.
So, for photo camera together with me filming for videos, or as a C cam in broadcasting, the R6 seems great for me.
Hope this explains it clear, but please ask if you have questions or thoughts as I am more than happy to answer.
